Description

  The present invention relates to a game device, a game management device, a game system, a game control method, and a program that execute various games.

  There is a game in which a player owns objects such as various items and characters in the virtual game space, and the player can use such objects in the game. In such a game, since the game development of whether or not the player can carry the game as expected usually differs depending on what kind of object the player owns, the player has the kind of object he wants. Try to collect objects.

  For example, in some baseball games, players can collect player characters to form their own team and play a team battle game with other teams. In this case, the player tries to obtain a desired player character in order to form an ideal team envisioned by the player. However, in general, it is not easy to obtain an object such as a character desired by the player in the virtual game space.

  Therefore, in a conventional game system, a plurality of game devices are communicably connected so that a plurality of players can exchange objects owned by each other with each other. Some of them can be obtained from other players (see Patent Document 1).

Japanese Patent No. 4393267

  However, in the above conventional configuration, since it is necessary to exchange objects with other players, other players do not have the object desired by the player, or other players have the object. However, the player cannot obtain the desired object if he / she does not make the exchange target. Therefore, the object exchange with the other players is tried many times, but the object desired by the player cannot be obtained at one time, and the player is dissatisfied with the exchange between the players. There was also.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a highly entertaining game device and game management device capable of realizing character exchange that eliminates dissatisfaction during exchange between conventional players. A game system, a game control method, and a program are provided.

  (1) A game device according to one aspect of the present invention is a game device that executes a game in which a player-owned character can be exchanged for another character in order to achieve the above object. Character managing means for managing characters in the game; exchangeable character presenting means for determining a replaceable character exchangeable with the owned character based on the owned character and presenting the replaceable character on the screen; The replaceable character presenting means predicts the character that the player desires to obtain by analyzing the possessed character, and all characters in the game managed by the character managing means based on the prediction result The exchangeable character is determined from the list.

  According to this configuration, the owned characters owned by the player, for example, player characters such as pitchers and fielders in the baseball game are managed by the character management means. The players can exchange characters that can be exchanged with the exchangeable characters that are presented from the game device side instead of the characters exchanged between the players. In this character exchange, the exchangeable character presenting means determines the exchangeable character to be presented from the game device side based on the character owned by the player, so that the CPU in the game device wants the player to exchange. Characters can be analyzed to determine replaceable characters. The exchangeable character determined in this way is displayed on the screen, for example, and presented to the player. Further, as will be described later, a character exchange condition for exchanging the exchangeable character and the player's owned character is set on the game device side, and the character exchange condition is also displayed on the screen and presented to the player.

  As described above, in the conventional exchange between players, when the other player does not have the character desired by the player, or even if the other player has it, it will not be the subject of exchange. However, it is difficult to obtain the desired character, and if such a situation continues, the player may be dissatisfied with the exchange between the players. On the other hand, in the present game device, as described above, the replaceable character presenting means predicts (analyzes) the character that the player desires to obtain by analyzing the possessed character, and based on the prediction result, the character Since the exchangeable character is determined from all the characters in the game managed by the management means, it is possible to analyze (predict) the character that the player desires to exchange and select the exchangeable character, Smooth character exchange that suppresses dissatisfaction at the time of exchange between conventional players can be realized.

  (2) In the configuration of (1), the game is a group game including a plurality of the owned characters, and the replaceable character presenting means calculates an average value of the basic ability values of the owned characters within the group. An average value calculating means for each position, an insufficient position specifying means for specifying a position having the lowest average value calculated by the average value calculating means as an insufficient position, and an insufficient position specified by the insufficient position specifying means Position determining means for determining a position so that a lottery is drawn with a higher probability than other positions, and the replaceable character presenting means uses the character at the position determined by the position determining means as a replaceable character. It is preferable to present it on the screen.

  According to this configuration, positions (for example, a starting pitcher, a relay / repressing pitcher, an infielder) in a group including a plurality of player-owned characters (for example, a baseball team formed by player characters owned by the player in a virtual space) , Outfielders, catchers, etc.). This shortage position is specified by calculating the average value of the basic ability values of the characters owned by the player for each position in the group by the average value calculation means, and selecting the position with the lowest calculated average value as the shortage position. This is realized by the specifying means specifying the shortage position. Here, the basic ability value represents the height of the basic ability of each character (for example, in the case of a baseball game, the pitcher ability and fielder ability of the player character), and the average value of the basic ability value is the highest. The low position is a position that is insufficient in terms of strength, and can be expected to be a position that the player desires to obtain through exchange.

  This shortage position is drawn at a higher probability than other positions when determining the position of the exchangeable character. In this way, in this game apparatus, a character that the player wants to exchange is predicted by specifying the insufficient position based on the player's possessed character, and the character at the insufficient position is replaceable with the character at other positions. It is easy to be presented on the screen. In short, processing is performed to provide options that can compensate for the weaknesses of the group of players. This realizes smooth character exchange that more effectively suppresses dissatisfaction during the exchange between conventional players.

  (3) In the configuration of (2) above, a character exchange condition for exchanging the exchangeable character and the possessed character presented by the exchangeable character presenting means is set, and the character exchange condition is displayed on the screen. The exchange condition presenting means further presents the probability that the shortage position specified by the shortage position specifying means is presented as the character exchange condition as a condition for each other position. It is preferable to set it lower than the probability.

  According to the above configuration, the character exchange condition for exchanging the exchangeable character presented by the exchangeable character presenting means and the player-owned character is set by the exchange condition presenting means, and the character exchange condition is also displayed on the screen. And is presented to the player.

  As described above, when the exchangeable characters and the exchange conditions are presented from the game device side, the player confirms them on the screen, and determines whether or not to exchange the presented exchangeable characters with the player's own characters. Will be considered. When the owned character that satisfies the character exchange condition presented by the game apparatus is selected by the player, the exchange between the owned character and the exchangeable character presented by the game apparatus can be established.

  Here, since the shortage position is a position where the strength is insufficient compared to other positions, it can be analyzed (predicted) that the player does not want to be exchanged. When a position that a player does not want to be exchanged is presented as an exchange condition, it is difficult to respond to the exchange condition. Therefore, the frequency with which such an exchange condition is presented from the game device may be reduced. desirable. Therefore, the game device sets the probability that the insufficient position is presented as the condition for character exchange by setting the probability lower than the probability that the other positions are presented as a condition, thereby making it difficult to present the insufficient position as the character exchange condition. Thus, smooth character exchange is realized.

  (4) In any one of the constitutions (1) to (3), the owned character belongs to any one of a plurality of predetermined groups, and the replaceable character presenting means is the most Group determination means for identifying a group to which many of the owned characters belong, and group determination for determining a group so that the group identified by the belonging group identification means is selected with a higher probability than other groups It is preferable that the replaceable character presenting means presents the characters belonging to the group determined by the group determining means on the screen as replaceable characters.

  According to this configuration, each character owned by the player belongs to one of a plurality of predetermined groups. For example, in a baseball game, a plurality of teams corresponding to 12 professional Japanese baseball teams in the real world also exist in the virtual space as a group, and each character belongs to one of these teams. The group having the largest number of groups to which the player's owned characters belong is specified by the belonging group specifying means. The group specified in this way can be expected to be a favorite group that the player actively collects, that is, a group to which the player wants to obtain by exchange.

  The group specified by the belonging group specifying means is selected with a higher probability than other groups when determining the belonging group of the exchangeable character. In this way, in this game apparatus, a player's favorite group is predicted based on the player's possessed characters, and the characters of the group are more easily presented on the screen as exchangeable characters than the characters of other groups. Thus, smooth character exchange that more effectively suppresses dissatisfaction during the exchange between conventional players is realized.

  (5) In the configuration of (4) above, a character exchange condition for exchanging the exchangeable character presented by the exchangeable character presenting means and the owned character is set, and the character exchange condition is displayed on the screen. The exchange condition presenting means further presents the probability that the group specified by the belonging group specifying means is presented as the character exchange condition based on the probability that the other group is presented as a condition. Is also preferably set low.

  Here, since the group specified by the belonging group specifying means is expected to be a favorite group of the player as described above, it is a group that the player thinks that the player does not want to be exchanged if he turns it back. It can be analyzed (predicted). When a group that a player does not want to be exchanged is presented as an exchange condition for a player, it is difficult to respond to the exchange condition. Therefore, the frequency with which such an exchange condition is presented from the game device may be reduced. desirable. Therefore, the game apparatus sets the specified group by setting the probability that the group specified by the belonging group specifying means is condition-presented as a character exchange condition lower than the probability that other groups are condition-presented. Is difficult to be presented as a character exchange condition, thereby realizing a smooth character exchange.

  (6) A game management device according to another aspect of the present invention is a game management device that communicates with a terminal device of a player and manages a game in which the owned character owned by the player can be exchanged with another character. Then, based on the character management means for managing the characters in the game, the exchangeable character presentation for determining the exchangeable character exchangeable with the possession character based on the possession character and presenting the exchangeable character on the screen The exchangeable character presenting means predicts a character that the player desires to obtain by analyzing the possessed character, and based on the prediction result, all the characters in the game managed by the character managing means The replaceable character is determined from the characters.

  According to this configuration, the game management device accepts access from the terminal device of each player via the network and provides a game service to each player via the network. For example, a network connection such as a server It is composed of possible information processing devices. Examples of the game service provided to each player by the game management apparatus include services such as a social game that the players can play while cooperating with each other or communicating.

  In addition, the game management device includes the character storage means and the character exchange means described in (1) above, and presents a replaceable character on the screen of the player's terminal device. According to this configuration, as in the configuration of (1) above, the exchangeable character to be presented to the player by the game management device is determined based on the player's own character, so the character that the player desires to exchange is analyzed ( Therefore, it is possible to select characters that can be exchanged, and smooth character exchange that suppresses dissatisfaction at the time of exchange between conventional players can be realized.

[Outline of game device]
A game device according to an embodiment of the present invention is applied to a game in which a player can own a character in a virtual space, and the player can use a character owned by the player in the game. . As an example of the game, a sports game in which a player owns a player character in a virtual space and plays a game in the virtual space using the player character can be cited. In a baseball game, which is an example of a sports game, a player forms his / her team by player characters such as a pitcher character or a fielder character that he / she owns, It is possible to play against the opponent team formed by the player. In the present embodiment, this baseball game will be described below as an example.

  In the game device according to the present embodiment, an example is shown in which a player character (owned character) owned by a player is displayed on a screen in a card format in which the form of the player character is visible. For example, as shown in FIG. 9, each player character owned by the player has a player character form, a player name, a position symbol (for example, “P” represents a pitcher), a basic ability value (for example, ☆ number), and the like. Displayed on the screen as a player card. That is, in this embodiment, the player has a player card and can collect or exchange the player card, and the player character is managed as a player card in the game. Then, the player can form an original team with the collected player cards and enjoy the game of the baseball game. Note that the player character in the game is composed of polygons or the like in the virtual game space, and moves based on the operation of the player.

  In the game device according to the present embodiment, the CPU of the game device analyzes the player character owned by the player, and determines the exchangeable character that can be exchanged with the player character in the game device. Possible characters and exchange conditions are presented on the screen. For example, as shown in FIG. 6, the game device can present a replaceable character determined based on a player card owned by the player as a replaceable card on a predetermined screen, and the player can select the replaceable card. Like that. Further, as shown in FIG. 7, the game apparatus presents on the screen an exchange condition (character exchange condition) for exchanging the exchangeable card selected by the player and the player card owned by the player. Then, for example, as shown in FIG. 9, on the player card list display screen owned by the player, when the player selects a player card that satisfies the exchange condition, the game apparatus establishes character exchange. Details of FIGS. 6, 7 and 9 will be described later.

  Thus, in this embodiment, the player does not exchange characters with other players, but exchangeable cards (exchangeable characters) presented by the CPU of the game apparatus and player cards (players) owned by the player Character). In the game device according to the present embodiment, when determining a replaceable card based on a player card owned by the player, the CPU predicts a card that the player desires to replace, and the predicted card is a replaceable card. As a result, it is possible to realize smooth character exchange that suppresses dissatisfaction during the exchange between the conventional players described above. Details of the configuration of the game device according to the present embodiment will be described below.

The buffers 14 to 16 correspond to the storage areas of the RAM 5 or the extended memory, respectively.

  The graphics data generation processor 3 serves as a so-called coprocessor of the CPU 1, and performs coordinate conversion and light source calculation, for example, calculation of fixed-point format matrices and vectors by parallel processing. The main processing performed by the graphics data generation processor 3 is based on the coordinate data, movement amount data, rotation amount data, and the like of each vertex in the two-dimensional or three-dimensional space of the image data supplied from the CPU 1. There are a process of obtaining address data of a processing target image on a predetermined display area and returning it to the CPU 1, a process of calculating the brightness of the image according to a distance from a virtually set light source, and the like.

  The interface circuit 4 is used for an interface of a peripheral device, for example, a pointing device such as a mouse or a trackball. The RAM 5 is used as a main memory. The ROM 6 stores program data that is an operating system of the game apparatus 100.

  The decompression circuit 7 performs decompression processing on a compressed image compressed by intra coding in accordance with the MPEG (Moving Picture Experts Group) standard for moving images and the JPEG (Joint Photographic Experts Group) standard for still images. This decompression processing includes decoding processing (decoding of data encoded by Variable Length Code), inverse quantization processing, IDCT (Inverse Discrete Cosine Transform) processing, intra image restoration processing, and the like.

  The drawing processor 10 performs a drawing process on the buffer 14 based on a drawing command issued by the CPU 1 every predetermined time (for example, 1/60 second which is one frame time). The buffer 14 is constituted by a RAM, for example, and is divided into a display area (frame buffer) and a non-display area. The display area is composed of a development area for image data to be displayed on the display surface of the television monitor 21. The non-display area is composed of storage areas such as data for defining skeletons, model data for defining polygons, animation data for causing the model to move, pattern data indicating the contents of each animation, texture data, and color palette data. . Here, the texture data is two-dimensional image data, and the color palette data is data for designating a color such as texture data. The CPU 1 reads these data from the recording medium 300 at once or in a plurality of times according to the progress of the game, and records them in the non-display area of the buffer 14 in advance.

  The audio processor 11 stores ADPCM (Adaptive Differential Pulse Code Modulation) data read from the recording medium 300 in the buffer 15 as a sound source. For example, the audio processor 11 reads ADPCM data from the buffer 15 based on a clock signal having a frequency of 44.1 kHz, and performs processing such as pitch conversion, noise addition, envelope setting, level setting, and reverb addition on the ADPCM data.

In this case, as the recording medium 300, a DVD-ROM, a CD-ROM, a hard disk, an optical disk, a flexible disk, a semiconductor memory, or the like is used. The recording medium drive 17 reads image data, audio data, and program data from the recording medium 300 and supplies the read data to the decoder 12. The decoder 12 performs error correction processing using ECC (Error Correction Code) on the data read by the recording medium drive 17 and supplies the processed data to the RAM 5 or the audio processor 11.

  The memory 18 is an auxiliary storage device, and has a nonvolatile storage area for storing various game parameters and the like in order to maintain the game state at the time of interruption when the game is interrupted, for example. The memory 18 can store game programs and various data. As this memory 18, for example, a card-type memory or a hard disk can be used.

  The controller 19 is an operation device used by a player who is an operator to input various operation commands, and sends an operation signal corresponding to the operation of the player to the CPU 1 via the interface circuit 13. The controller 19 is used, for example, to give the CPU 1 a command for moving a character or cursor up and down, left and right on the screen of the television monitor 21.

  Next, a schematic operation of the game apparatus 100 will be described. When the game apparatus 100 is turned on, the CPU 1 instructs the recording medium drive 17 to read the game program from the recording medium 300 based on the operating system stored in the ROM 6. Image data, audio data, and program data read from the recording medium 300 by the recording medium drive 17 are supplied to the decoder 12 and subjected to error correction processing.

  The image data subjected to the error correction process is supplied to the expansion circuit 7 via the bus line 2 and subjected to the above-described expansion process. Thereafter, the image data is supplied to the drawing processor 10 and written into the non-display area of the buffer 14 by the drawing processor 10. The audio data that has been subjected to error correction processing by the decoder 12 is written into the buffer 15 via the RAM 5 or the audio processor 11. The program data that has been subjected to error correction processing by the decoder 12 is written into the RAM 5.

Etc.). This level indicates the level (strength) of the player in multiple levels. For example, there are 20 levels from “0” that is the weakest level to “19” that is the strongest level. It is given to the player. Further, when the global ranking, the national ranking, or the ranking within a specific region is determined based on the ability evaluation level of the player, the ranking information is also stored in the memory 18 together with the rank information. This level information can be used in the exchangeable card strength determination process described later.

  The point / currency storage unit 43 stores points and currency (in-game coins) owned by the player in a predetermined area of the memory 18. Here, the points and the currency can be used to obtain various items and player cards in the virtual game space, and can be acquired by the player by playing the game. For example, the higher the difficulty level of the game (the stronger the opponent of the game), the more points and currency that can be acquired. Also, by winning the game, you can earn more points and currency than when you draw or lose. The acquired points and currency can be used for purchasing various items and player cards, for example, in a shop in the virtual game space. Further, the acquired points and currency may be used to purchase player cards exhibited by other players in a bazaar in the virtual game space.

  The owned card storage means 44 stores a player card (owned character) owned by the player in a predetermined area of the memory 18. As described above, the character information storage unit 31 also stores image information, basic ability values, and the like of the player character in association with the character ID. Therefore, the possessed card storage means 44 stores only the character ID as information on the player card owned by the player. Then, the player information management means 40 manages the player cards owned by the player by reading out the basic ability value corresponding to the character ID stored in the possessed card storage means 44 from the character information storage means 31. doing.

  In the present embodiment, when a player executes a game mode in which an original team is formed for the first time on the game apparatus 100 and performs a game, a predetermined number (for example, 30) of player cards is given to the player. ing. Thereafter, the player can additionally own the player card by purchasing the player card using the currency in the game acquired as described above. Note that a limit may be set on the number of player cards that a player can own. In the present embodiment, the player can own 30 to 140 player cards, and the possessed card storage means 44 secures a storage area for a maximum of 140 player cards in the memory 18.

  The player card exchange means 50 has a player card exchange processing function for exchanging a player card owned by the player with another player card. The player card exchange means 50 includes exchangeable card presentation means 51 (exchangeable character presentation means), exchangeable card selection means 52 (exchangeable character selection means), exchange condition presentation means 53, exchange target card selection means 54 (exchange). Target character selection means), exchange execution means 55, and random number generation means 56.

  The exchangeable card presenting means 51 has a function of determining an exchangeable card exchangeable with the player card based on the player card owned by the player and presenting the exchangeable card on the screen. That is, in game device 100 of the present embodiment, CPU 1 determines a replaceable card, and CPU 1 presents the replaceable card to the player. The exchangeable card presenting means 51 analyzes a player card owned by the player, predicts a player card that the player desires to exchange, and selects an exchangeable card reflecting the prediction. .

  For example, the exchangeable card presenting means 51 predicts a player card team (affiliated team) that the player wishes to exchange based on a player card possessed by the player, and the player card of the predicted player team is the other player's team card. It is made easier to be presented on the screen as a replaceable card than a player card. Moreover, the exchangeable card presenting means 51 predicts the position of the player card that the player desires to exchange by specifying the shortage position based on the player card owned by the player, and the player card of the predicted position is determined. It is made easier to be presented on the screen as a replaceable card than the player cards in other positions.

  An example of a screen on which the exchangeable card presenting means 51 presents the exchangeable card to the player is shown in FIG. The exchangeable cards 101 selected by the exchangeable card presenting means 51 are displayed as a list as “current exchangeable cards”. More detailed configuration and operation of the exchangeable card presenting means 51 and details of the screen of FIG. 6 will be described later.

  The exchangeable card selection means 52 causes the player to select an arbitrary exchangeable character 101 from the choices of the exchangeable character 101 presented by the exchangeable card presentation means 51. For example, the exchangeable card selection means 52 recognizes the operation input signal of the controller 19 and moves the frame-like cursor 104 surrounding the card shown in FIG. 6 to move the arbitrary exchangeable card 101 to the player. This can be realized by selecting with. In order to determine the exchangeable character 101 selected by the player as an object of exchange processing, for example, the player operates the controller 19 and selects the determination button 113.

  The exchange condition presenting means 53 shown in FIG. 2 sets an exchange condition (character exchange condition) for exchanging the exchangeable card presented by the exchangeable card presentation means 51 and the player card owned by the player. It has a function of presenting the exchange condition on the screen. The number of player cards owned by the player as exchange conditions by the exchange condition presenting means 53 for one exchangeable card may be one or plural. In the present embodiment, a mode in which 1 to 3 player cards are obtained as exchange conditions for one exchangeable card will be described.

  FIG. 7 shows a screen example in which the exchange condition presenting means 53 presents the exchange conditions to the player. The figure shows an example of a screen in which two player cards (exchange cards 1 and 2) are requested for one exchangeable card. In this case, the player has a total of two players cards, one player card that satisfies the exchange card 1 condition and one player card that satisfies the exchange card 2 exchange condition. It is necessary to select it as an exchange target. More detailed configuration and operation of the exchange condition presenting means 53 and details of FIG. 7 will be described later.

  The exchange target card selection means 54 causes the player to select a player card to be exchanged with the exchangeable card from among the player cards owned by the player. For example, as shown in FIG. 9, the exchange target card selection means 54 displays a list of player cards 141 owned by the player on the screen, and the CPU 1 recognizes the operation input signal of the controller 19 and moves the cursor 104. This can be realized by causing the player to select an arbitrary player card 141 with the cursor 104.

  By the way, in this embodiment, each player card possessed by the player can be registered in any one group of the first army, the second army, or the third army. Each army has a maximum number of player cards that can be registered. For example, there are 28 one-arm registered player frames, 42 two-arm registered player frames, and 70 three-arm registered player frames. Usually, the player registers the player card of the player character that he / she wants to use in the game with the first army, and registers with the second army or the third army the player player card leaked from the first army frame.

  Therefore, in the present embodiment, the replacement target card selection means 54 first displays the army selection screen shown in the screen example of FIG. 8, and selects the player card to be replaced from either the second army or the third army group. The player can select whether to do. In this way, rather than displaying a list of all the player cards (up to 140) owned by the player, first select a grouped army and list the player cards by narrowing down to the selected army. The display makes it easier for the player to select a card. In addition, many of the player cards registered in one army are players cards that the player likes among the player cards owned by the player, and many of the player cards that are exchange personnel are in the second army or the third army. Existing. Therefore, first, an army selection screen shown in the screen example of FIG. 8 is displayed so that a player card to be exchanged can be selected from either the second army or the third army. If, for example, the second arm button 131 is selected on this army selection screen, the screen shifts to the above-described display screen of FIG. 9, and a list of player cards registered as second army players is displayed. However, since a player card to be exchanged may exist in one army, any one of the first army to the third army may be selected on the army selection screen in FIG.

  As shown in FIG. 2, the replacement target card selection means 54 includes an extraction means 54a and an extraction display means 54b. The extracting means 54a has a function of extracting a player card that satisfies the exchange condition presented by the exchangeable card presenting means 51 from the player cards owned by the player. The extraction display means 54b has a function of displaying the player card extracted by the extraction means 54a on the screen in distinction from the player card that does not satisfy the exchange condition.

  An example of distinguishing and displaying player cards that satisfy the exchange condition and player cards that do not satisfy the exchange condition is to vary the brightness of the player card. For example, as shown in FIG. 9, the brightness of the player card 141 that satisfies the replacement condition is increased so that the card is displayed brighter, while the brightness of the player card 141 that does not satisfy the replacement condition is decreased. Yes. As a result, the player can clearly see which player card 141 satisfies the exchange condition. As another example, the color of the player card 141 is changed depending on whether or not the exchange condition is satisfied, or the size of the player card 141 is changed (for example, larger than the player card not satisfying the player card that satisfies the exchange condition). The player card 141 that satisfies the exchange condition may be clarified by, for example. In the screen example of FIG. 9, the player card 141 that satisfies the replacement condition is displayed in color, while the player card 141 that does not satisfy the replacement condition is displayed in gray and the color is also different. In addition, since the player card 141 that does not satisfy the replacement condition cannot be used as a replacement object in the first place, it is desirable that the player card 141 cannot be selected as a gray-out display.

  Thus, even if the player owns a large number of player cards, the replacement target card selection means 54 distinguishes and displays the player cards that satisfy the replacement conditions and the player cards that do not satisfy the replacement conditions, A player card satisfying the condition can be easily found, and the selection operation of the player card to be exchanged can be performed accurately and smoothly.

  The exchange execution means 55 shown in FIG. 2 establishes an exchange between the player card and the exchangeable card when a player card satisfying the exchange condition is selected by the exchange target card selection means 54, and stores the possessed card storage means 44. It has a function to update the contents to the contents after the exchange is established.

  The random number generation unit 56 generates a random number and outputs the random number value to the exchangeable card presentation unit 51 and the exchange condition presentation unit 53. A general pseudo-random number generation algorithm can be used to generate this random number. The exchangeable card presenting means 51 uses the random number generated by the random number generation means 56 in the process of determining the base, position, strength, etc. of the exchangeable card.

The exchange condition presenting means 53 uses the random number generated by the random number generating means 56 in the process of determining the number of cards necessary for exchange. Details of processing using random numbers in the exchangeable card presenting means 51 and the exchange condition presenting means 53 will be described later.

  Next, a more detailed configuration of the exchangeable card presenting means 51 will be described with reference to the functional block diagram of FIG. The exchangeable card presenting means 51 includes a team determining unit 61, a position determining unit 62, a strength determining unit 63, a replaceable card selecting unit 64, and a replaceable card display unit 65.

  In the present embodiment, each player character in the virtual game space belongs to any one of a plurality of predetermined teams (groups). For example, a plurality of teams corresponding to 12 professional Japanese baseball teams in the real world (or 30 teams in the case of major league games) also exist in the virtual game space, and each player character I belong to one of the teams. In the present embodiment, the following description will be continued assuming that there are 12 teams T1 to T12 in the virtual game space.

  The team determining unit 61 has a function of determining a team (group) to which the exchangeable card (player character) belongs. When determining the team, the team determining unit 61 predicts the team of the player character that the player wants to exchange, and makes it easier to select the team in a more probable manner than other teams. In order to realize this, the team determining unit 61 includes a team specifying unit 66 (belonging group specifying unit) and a team determining unit 67 (group determining unit).

  The team identification unit 66 identifies the team to which the player characters of the most player cards belong based on the player cards owned by the player. The player can collect player cards of a specific team that he / she likes by the player card exchange function of the game apparatus 100, the bazaar in the virtual game space, and the like. Therefore, if the player card possessed by the player is analyzed and the team to which the most player characters belong is specified, the favorite team that the player has collected, that is, the player desires to obtain it by exchange. The player's character team can be predicted.

  Further, in the present embodiment, when the player executes a game mode in which the game team 100 first forms an original team and plays a game, any of the teams T1 to T12 is set as the own team (or base team). It can be selected. In this case, since the team selected as the player's own team can be expected to be the player's favorite team, the team identification unit 66 identifies the team as belonging to the player character that the player wishes to exchange. May be.

  Note that the player can form a completely original team without selecting any of the teams T1 to T12 as the own team. When a player forms an original team, regardless of whether or not to select his own team, the team to which the most player characters belong is based on the player card owned by the player as described above. By specifying, it is possible to accurately predict the team desired by the player.

  The team determining unit 67 has a function of determining the team based on the probability so that the team specified by the team specifying unit 66 is selected with a higher probability than the other teams. The team determining unit 67 determines a team based on a random number generated by the random number generating unit 56, for example. Then, the team determining means 67 improves the probability that the team specified by the team specifying means 66 is selected when the teams are selected by random numbers, more than the probability that each other team is selected. For example, in a range (minimum value to maximum value) that can be acquired as a random number value, the random number value for which the team specified by the team specifying means 66 is drawn is 20% (11/55), and the other 11 teams Each of the random numbers is weighted so that the random number drawn is about 7.27% (4/55), which is lower than the random number.

  The weighting of the lottery probability is not limited to the above example. If the probability that the team specified by the team specifying means 66 is selected is higher than the probability that each other team is selected, any lottery probability It can be. However, if the probability that the team specified by the team specifying means 66 is drawn too much is too high, the player card of the team expected to be obtained by the player may be easily presented as a replaceable card. In this case, the player can easily obtain the player card of the desired team by the exchange process of the game apparatus 100. In order for the player to feel the fun and enjoyment of collecting his / her favorite player cards, think about the balance so that the player cards are not too easy to obtain and are not too difficult to obtain. It is desirable. Therefore, in consideration of the above-mentioned balance, in this embodiment, the team is more than the case where the lottery probability is not weighted (that is, the lottery probability of each of the 12 teams is approximately 8.33% (1/12) uniform). The probability that the team specified by the specifying means 66 is drawn is increased by about 10%, and is set to 20% as described above.

  Next, variations of the exchangeable card team determination by the team determination unit 61 will be described. There may be a plurality of favorite teams of the player among the plurality of teams T1 to T12 existing in the virtual game space. For example, when the teams T1 to T12 are divided into two leagues as in the real world Japan professional baseball and major leagues, the player may have a favorite team in each league. Therefore, the team specifying means 66 of the team determining unit 61 specifies not only the most numerous teams among the player cards owned by the player but also the second most numerous teams. The team determining means 67 sets the weights of the lottery probabilities of the teams, for example, 20% for the most numerous teams, 10% for the second most numerous teams, and 7% for each other team, and the lottery probabilities for the top two teams. Is set higher than the other lottery probabilities. Furthermore, it is possible to specify up to the nth largest number of teams among player cards owned by the player, and set the lottery probability of the top n teams higher than other lottery probabilities.

  The position determination unit 62 has a function of determining the position of the exchangeable card (player character). In determining the position, the position determining unit 62 predicts the position of the player character that the player desires to exchange by specifying the insufficient position based on the player card owned by the player, It is easier to be selected probabilistically than each position. In order to realize this, the position determining unit 62 includes an average strength calculating unit 68 (average value calculating unit), an insufficient position specifying unit 69, and a position determining unit 70.

  The average strength calculation means 68 calculates the average value of the strength (basic ability value) represented by the number of ☆ player cards owned by the player for each position. In the case of the baseball game of the present embodiment, for example, (1) starting pitcher, (2) relay / repressing pitcher, (3) infielder, (4) outfielder, (5) strength for each of the five positions of the catcher The average value of is calculated. In addition, the position division for calculating the average value is not limited to this, for example, starting pitcher, relay pitcher, hold pitcher, first base, second base, shortstop, third base, right wing, middle wing, left wing, The average strength may be calculated for each position of the catcher. In addition, when employing a designated batter who is a player specializing in attacks in a baseball game, the designated batter may be included in one of the positions, and the average strength for each position may be calculated.

  The deficient position specifying unit 69 specifies a position having the lowest average strength calculated by the average strength calculating unit 68 as a deficient position. Since the shortage position specified in this manner has a lower strength than the other positions, it can be predicted that the player desires to obtain it by exchange.

  Next, the variation of the insufficient position specification by the insufficient position specifying means 69 will be described. The insufficient position specifying means 69 may specify a position that does not satisfy the reference number (a position where the number is initially insufficient) as an insufficient position. The reference number in this case is, for example, “6” for the starting pitcher, “8” for the relay / restraining pitcher, “6” for the infielder, “5” for the outfielder, and “3” for the catcher. May be different. When there are a plurality of positions that do not satisfy the reference number, one position that is not the most reference number may be specified as a deficient position, or all of the plurality of positions may be specified as deficient positions. .

  Further, another variation for specifying the insufficient position will be described next. When the average strength calculation means 68 calculates the average strength for each position, the average value of the strength (☆ number) of the top n player cards with the largest number of ☆ in each position is calculated. (The value of n can be varied depending on the position). Then, the shortage position specifying means 69 specifies the position having the lowest average strength of the top n sheets as the shortage position. This is because a position where the top n player cards are fulfilled is likely to be satisfied by the player as the strength of the position, and the player cards below it are treated as exchange personnel. Therefore, the player cards lower than the top n cards in each position are excluded from the target for specifying the insufficient positions. In addition, if there are a lot of lower player cards in a position where the top n player cards are substantial, the average strength of the entire position will be greatly reduced as a result. Player cards that are lower than the top n positions are excluded from the targets for specifying the insufficient positions.

  The position determining unit 70 has a function of determining the position based on the probability so that the insufficient position specified by the insufficient position specifying unit 69 is selected with a higher probability than each of the other positions. The position determining unit 70 determines a position based on, for example, a random number generated by the random number generating unit 56. Then, the position determining means 70 improves the probability that an insufficient position is selected when determining a position based on a random number, compared to the probability that other positions are selected. For example, within a range that can be acquired as a random number value, the random value from which the insufficient position is drawn is 30% (12/40), and the other four positions are drawn at a lower random value. The probability of random lottery is weighted so as to be 17.5% (7/40).

  The weighting of the lottery probability is not limited to the above example. However, as in the case of the team decision, it is desirable to consider the aforementioned balance so that the probability that the insufficient position will be drawn is not too high. In consideration of this balance, in this embodiment, the insufficient positions are drawn more than when the lottery probabilities are not weighted (that is, when the lottery probabilities of the five positions are 20% (1/5) uniform). The probability is increased by 10% to 30%.

  The strength determining unit 63 has a function of determining the number ☆ which is the strength of the exchangeable card presented by the CPU 1. The strength determination unit 63 includes a strength determination probability table storage unit 71, a probability table selection unit 72, and a strength determination unit 73.

  The strength determination probability table storage means 71 stores a strength determination probability table for determining the number of ☆ which is the strength of the exchangeable card in a predetermined storage area. Further, the strength determination probability table storage means 71 temporarily stores the strength determination probability table in the work area of the RAM 5 as the main storage device as necessary during the game.

  13A to 13C show examples of the strength determination probability table. FIG. 13A shows an example in which the probability table for determining the strength of a replaceable card changes in accordance with the degree of progress of the tournament (the level of the tournament or the difficulty level) executed in the virtual game space. Here, the tournament held in the virtual game space will be described below.

  In the baseball game of the present embodiment, an original team is formed by player cards owned by the player, and the player directs the original team from the manager's position (or while the player operates the player character of the original team). , A play mode is provided that can participate in various tournaments (for example, tournament-style game tournaments). In this play mode tournament, for example, as shown in FIG. 13A, there are seven tournaments of Grand Prix 1 to Grand Prix 7, and the player can only participate in Grand Prix 1 at first. And, in principle, you can qualify for the Grand Prix 2 tournament only if you win the Grand Prix 1 tournament. Similarly, it is possible to participate in the Grand Prix (n + 1) only when the Grand Prix n is won, and the level (difficulty level) of the tournament increases in the order of Grand Prix 1 to Grand Prix 7. In addition, the eligibility to participate in each tournament is not limited to the above example, and the tournament level only needs to increase in the order of Grand Prix 1 to Grand Prix 7.

  In the present embodiment, after a player participates in any tournament and the tournament ends, the player card exchange means 50 determines (updates) the lineup of exchangeable cards presented on the screen of FIG. It has become.

  In the example of FIG. 13A, the probability for determining the strength of the exchangeable card depending on which level the tournament has participated in the tournament in the virtual game space named Grand Prix 1 to Grand Prix 7 as described above. The table is different. For example, when a player participates in the Grand Prix 1 tournament, the probability that an exchangeable card will have a probability of 10 to 24 is 10%, a probability of 25 to 54 is 45%, and a probability of 55 to 79 Is 40%, and the probability of ☆ 80-99 is 5%. Also, for example, when a player participates in a Grand Prix 7 tournament, the probability of becoming ☆ 10-24 is 0%, the probability of ☆ 25-54 is 5%, the probability of ☆ 55-79 is 50%, ☆ 80 The probability of becoming -99 is 45%, and the probability that a large ☆ number is selected as the strength of the exchangeable card increases. As described above, the strength determination probability table of FIG. 13A is set such that the higher the level of a tournament, the higher the probability that a large number of ☆ will be selected as the strength of a replaceable card.

  By the way, if a player can participate in a certain level of a tournament, it is expected that the player possesses a player card having a strength suitable for the level of the tournament.

Therefore, even if a small number of replaceable cards are presented to a player participating in a high level tournament, it is unlikely that the cards are eligible for replacement. Therefore, the strength determination probability table of FIG. 13A makes it easier for players participating in a higher level tournament to more easily select a stronger (☆ number) player card as a replaceable card. In addition, if players who participate in a tournament that is not so high can make it easy to obtain a large number of player cards by exchanging cards, they can easily win the tournament without suffering. This can damage the fun of the game. Therefore, a reasonable probability table corresponding to the level of the tournament is assigned so that an appropriate number of exchangeable cards can be easily selected according to the level of the tournament in which the player participates (the progress of the tournament). .

  Moreover, it can replace with FIG. 13A and can also use the strength determination probability table of FIG. 13B. The strength determination probability table in FIG. 13B shows an example in which the probability table for determining the strength of a replaceable card changes according to the level of the player's level. In the example of FIG. 13B, the range of each stage level of stages 0 to 3, stages 4 to 6, stages 7 to 9, stages 10 to 12, stages 13 to 15, stages 16 to 17, and stages 18 to 19 is shown in FIG. The same probability table as that of Grand Prix 1 to Grand Prix 7 is applied. That is, the strength determination probability table of FIG. 13B is set such that the higher the player's level, the higher the probability that a large number of ☆ will be selected as the strength of the exchangeable card.

  By the way, if the player is at a certain level, it is expected that the player possesses a player card having a strength suitable for the level. Therefore, even if a small number of replaceable cards are presented to a player with a high level, it is unlikely that the cards are subject to replacement. Therefore, in the strength determination probability table of FIG. 13B, the higher the player's level, the easier it is to select a stronger (large number of) player card as a replaceable card. Also, if a player whose level is not so high can easily obtain a player card with a large number of ☆ by exchanging cards, it will easily allow the promotion of the level. May impair the interest of Therefore, a reasonable probability table corresponding to the level is assigned so that an appropriate number of exchangeable cards can be easily selected according to the level of the player.

  Moreover, it can replace with FIG. 13A and FIG. 13B, and can also apply the strength determination probability table of FIG. 13C. The strength determination probability table of FIG. 13C determines the strength of the exchangeable cards according to the average strength (average value of the number) of all player cards (or player cards of one army) possessed by the player. An example in which the probability table for the change is shown. In the example of FIG. 13C, the average value is less than ☆ 25, ☆ 26-30, ☆ 31-35, ☆ 36-40, ☆ 41-45, ☆ 46-50, ☆ 51 The probability table similar to 1 to Grand Prix 7 is applied. That is, the strength determination probability table in FIG. 13C is set such that the greater the average strength of player cards owned by a player, the higher the probability that a large number will be selected as the strength of a replaceable card. Yes.

  Even if an exchangeable card with a small number of ☆ is presented to a player who has a large average value of the number of player cards owned, it is considered that the card is not likely to be exchanged. Therefore, the stronger the average strength of the player cards owned by the player, the easier it is to select a stronger (☆ number) player card as a replaceable card. Also, if a player whose average strength of player cards is not so large, if the player can easily obtain a large number of player cards by exchanging the cards, the team power will increase too rapidly. . Therefore, a reasonable probability table corresponding to the average strength is assigned so that a reasonable number of exchangeable cards can be easily selected according to the average strength of the player cards owned.

  The probability table selection means 72 shown in FIG. 3 is based on the strength determination probability table stored in the strength determination probability table storage means 71, the tournament in which the player participated, the player's rank, or the player card owned by the player. Select the probability table corresponding to the average strength. For example, when the strength determination probability table of FIG. 13A is applied and the tournament in which the player participates is Grand Prix 1, ☆ 10-24 is 10%, ☆ 25-54 is 45%, ☆ 55- The probability table in which 79 is 40% and ☆ 80 to 99 is 5% is selected.

  The strength determining means 73 applies the probability table selected by the probability table selecting means 72, and the number ☆ (the number range) that is the strength of the exchangeable card based on the random value generated by the random number generating means 56 To decide.

  The exchangeable card selection means 64 selects the player card of the player character that satisfies all the ranges of the team determined by the team determining unit 61, the position determined by the position determining unit 62, and the strength determined by the strength determining unit 63. As a replaceable card, the player is selected from all player characters in the game managed by the character management means 30. The exchangeable card selection means 64 includes exchangeable card storage means 64a for storing the selected exchangeable card in a predetermined storage area. Moreover, the exchangeable card display means 65 displays the exchangeable card selected by the exchangeable card selection means 64 on the screen as shown in FIG. 6, for example.

  Next, a more detailed configuration of the exchange condition presenting means 53 will be described with reference to the functional block diagram of FIG. The exchange condition presenting means 53 includes a necessary number determining means 81, a strength setting means 82 (basic ability value setting means), an exchange target selecting means 83, an exchange condition determining means 84, and an exchange condition display means 85.

  The necessary number determining means 81 has a function of determining the number (required number) of player cards necessary for exchange with a replaceable card. When determining the necessary number, the necessary number determining means 81 increases the probability that the necessary number increases as the strength (basic ability value) of the exchangeable card increases. In order to realize this, the required number determining means 81 includes a card number determination probability table storage means 86 (necessary number determination probability table storage means), a probability table selection means 87, and a number determination means 88.

  The card number determination probability table storage means 86 stores a card number determination probability table for determining the number of player cards necessary for exchange in a predetermined storage area. Further, the card number determination probability table storage means 86 temporarily stores a card number determination probability table in the work area of the RAM 5 as the main storage device as necessary during the game.

  FIG. 14 shows an example of the card number determination probability table. In the example of FIG. 14, when the strength of the exchangeable card presented by the exchangeable card presenting means 51 is from ☆ 10 to 24, the probability that the required number of player cards is one is 100%. In addition, when the strength of the exchangeable card is ☆ 25 to 54, the probability that the required number is 1 is 80%, the probability that it is 2 is 20%, and in the case of ☆ 55 to 79, The probability that the required number will be 1 is 40%, the probability that it will be 2 is 40%, the probability that it will be 3 is 20%, and in the case of 80-99, there is a probability that the required number will be 1 The probability of 30% and 2 sheets is 30%, and the probability of 3 sheets is 40%. Thus, the card number determination probability table is set such that the greater the strength of the exchangeable card, the higher the probability that the number of player cards required for exchange will increase.

  The probability table selection means 87 shown in FIG. 4 corresponds to the strength of the exchangeable card presented by the exchangeable card presentation means 51 from the card number decision probability table stored in the card number decision probability table storage means 86. Select a probability table. For example, when the exchangeable card strength is ☆ 74, the probability that the required number will be 1 in the card number determination probability table of FIG. A probability table with a probability of 20% is selected.

  The number determination means 88 applies the probability table selected by the probability table selection means 87, and determines the number of player cards necessary for exchange based on the random value generated by the random number generation means 56.

  The strength setting means 82 sets the strength (basic ability value) of each player card required for exchange with a replaceable card as the number of player cards required for exchange determined by the number determination means 88 increases. It has the function to do. That is, for exchange with one exchangeable card presented by the CPU 1 (presented by the exchangeable card presentation means 51), when n player cards owned by the player are required, the larger the number of n, the one player card By keeping the strength per hit low, the balance between the number of cards required for replacement and the strength is balanced.

  FIG. 15 illustrates the relationship between the number of player cards necessary for exchange with one exchangeable card and the strength of each player card (strength per player card). As shown in the example of FIG. 15, the strength setting means 82 determines the strength of each player card from the strength (☆ number) of exchangeable cards presented by the CPU 1 and the number of player cards required for replacement. calculate. That is, when one player card is required for exchange with one exchangeable card, the strength of the player card is calculated as the number ± 5 of the exchangeable card. As an example, considering the case where the exchangeable card has a strength of 74, the strength of the player card is set in the range of 69-79.

  Further, when two player cards are required for exchange with one exchangeable card, the strength of the player card is calculated as (number of exchangeable cards−number−10) ± 5. When the strength of the exchangeable card is ☆ 74, the strength of the two player cards necessary for exchange is set in the range of ☆ 59 to 69, respectively. In addition, when three player cards are required for exchange with one exchangeable card, the strength of the player card is calculated as (number of exchangeable cards−number−15) ± 5. When the strength of the exchangeable card is ☆ 74, the strengths of the three player cards necessary for exchange are set in the range of 54 to 64, respectively.

  As described above, the necessary number determining means 81 increases the probability that the number of necessary player cards (necessary number) will increase as the strength of the exchangeable card increases, and the required number tends to increase. Yes. The strength setting means 82 sets the strength of each player card to be lower as the number of player cards required for exchange is larger. That is, when a strong card is selected as the exchangeable card presented by the CPU 1, the number of player cards necessary for the exchange is likely to increase, and the strength of the player card per one is suppressed. It is. Thus, when a strong card with a large number of ☆ is presented by the CPU 1 as an exchangeable card, the player can exchange one-to-many with a player card with a smaller number of ☆. Therefore, even if the player does not have a large number of player cards that match the exchangeable cards, or even if you have a large number of player cards, you can exchange them. It becomes easy to do.

  The exchange target selection means 83 shown in FIG. 4 has a function of selecting a player card to be exchanged with a replaceable card from the player cards owned by the player stored in the possession card storage means 44. That is, in the stage before the CPU 1 finally determines the exchange conditions for obtaining the exchangeable card by exchange, the CPU 1 (the exchange object selection means 83 which is a function of the CPU 1) is a player card possessed by the player. Therefore, player cards that can be exchanged with exchangeable cards are selected in advance. The exchange target selection means 83 selects a player card that matches the “strength of each player card necessary for exchange” set by the strength setting means 82 from the player cards owned by the player. At this time, when there are a plurality of player cards that match the strength set by the strength setting means 82, the exchange target selection means 83 is based on a random number generated by the random number generating means 56, for example. Pick a random piece.

  The exchange condition determination unit 84 has a function of determining the exchange condition based on the player card selected by the exchange target selection unit 83. That is, the exchange condition determining means 84 is based on the player card so that the player card itself selected in advance by the exchange target selecting means 83 from among the player cards owned by the player satisfies the exchange condition. The exchange conditions are determined. The exchange condition determining means 84 includes an exchange condition item storage means 89, an exchange condition item selecting means 90, and an exchange condition setting means 91.

  In the present embodiment, as illustrated in FIG. 16, three basic exchange conditions of ☆ number trade, team trade, and ability trade are provided. The number trade is a request for a player card corresponding to the number of replaceable cards presented by the exchange target selection means 83 as an exchange condition. The team trade is a request for a player card of a specific team as an exchange condition. The ability trade is a request for a player card having a specific position or a specific ability as an exchange condition.

  Then, the replacement condition item storage unit 89 stores, for example, information on the replacement condition item list shown in FIG. 17 in a predetermined storage area. Identification information (exchange condition item ID) for uniquely identifying them is attached to each exchange condition item, and the CPU 1 can manage all the exchange condition items by the exchange condition item ID. . Among the basic exchange conditions, there are a plurality of exchange condition items for the ability trade. Regarding ability trade, exchange condition item ID = 3 is a common item for fielders and pitchers, but exchange condition item IDs 4 to 7 are dedicated items when player cards subject to exchange conditions are fielders. . Moreover, about exchange condition item IDs 8-14, it is an exclusive item in case the player card used as the object of exchange conditions is a pitcher. This exchange condition item list is an example, and other exchange condition items may be provided. For example, in the case of a fielder, the catching ability and shoulder strength, in the case of a pitcher, the change level of a change ball, etc. May be mentioned.

  The exchange condition item selection unit 90 selects one or more exchange condition items from the exchange condition item list stored in the exchange condition item storage unit 89. In the present embodiment, the replacement condition items 1 to 3 are selected by the replacement condition item selection means 90. The number of replacement condition items is not limited to 1 to 3, and can be set to any number. Then, the exchange condition item selected by the exchange condition item selection means 90 (or a combination of these when a plurality of exchange condition items are selected) is the exchange condition presented on the screen.

  The exchange condition setting means 91 sets exchange conditions so that the player card itself selected by the exchange object selection means 83 satisfies the exchange condition consisting of the exchange condition items selected by the exchange condition item selection means 90. For example, the player card selected by the exchange target selection means 83 is the player L (the strength of the player L is “☆ 65”, the belonging team “T2”, and other parameters are omitted), and the exchange condition item selection means 90 17, consider the case where two of the exchange condition items ID = 1 (a player with a number of ○ or more) and ID = 2 (a player with a belonging team of ○) are selected. In this case, since the exchange condition setting means 91 makes the player card of the player L owned by the player satisfy the exchange condition, for example, “a player with 65 or more players” and “a player whose team belongs to T2”. The exchange condition is set (see the exchange condition of the exchange card 1 in FIG. 7).

  In the above example, it is only necessary that the player card of the player L satisfies the exchange condition. For example, even if the exchange condition of “☆ 64 or more players” and “the player whose team is T2” is set. Good. However, if a value extremely lower than the parameter value (strength, etc.) of the player L is set as the exchange condition, other player cards with parameter values extremely lower than the player L will also satisfy the exchange condition. It will be. Therefore, it is desirable to set a value that is the same as or close to the parameter value of the player card (the player L card in this example) selected by the replacement object selection means 83 as the replacement condition.

  As another example, the player card selected by the exchange target selecting means 83 is player V (not shown) (player V strength “☆ 60”, team “T3”, ball speed “149 km / h”, ball “B” Rank ”, stamina“ G rank ”, dominant hand“ right pitcher ”, and other parameters are omitted), and the replacement condition item selection means 90 allows the replacement condition item ID = 2 (shown by the assigned team to be ○). Suppose that three players are selected, ID = 8 (player with a ball speed of ○ km / h or more) and ID = 14 (right pitcher or left pitcher). In this case, since the exchange condition setting means 91 makes the player card of the player V satisfy the exchange condition, for example, the exchange of “the player whose team is T3”, “the ball speed of 149 km / h or more” and “the right pitcher” Conditions are set (see the replacement conditions for the replacement card 2 in FIG. 7).

  In the above example, if ID = 13 (player with a stamina of ○ or higher) is selected by the exchange condition item selection means 90 instead of ID = 8 (player with a ball speed of ○ km / h or higher). In order to ensure that the player card of player V satisfies the exchange condition, an exchange condition that can be easily cleared, “player with stamina of G rank or higher” is set instead of “ball speed of 149 km / h or higher” become. In this case, many player cards other than the player V satisfy the exchange condition. An exchange condition advantageous to such a player may be set, but basically this may be allowed. However, it is never desirable that such exchange conditions that are advantageous to the player occur frequently. Therefore, when the exchange condition item selection means 90 selects the exchange condition item, if the ability trade is selected as the basic exchange condition, the player card selected by the exchange target selection means 83 (in this example, the player V card) It is desirable to weight the selection probabilities so that a higher parameter ability is more easily selected as an exchange condition item. That is, in the above example of player V, the exchange condition item for the ball speed (149 km / h) and the ball power (B rank) is set to have a higher selection probability than the stamina (G rank). is there.

  The exchange condition display means 85 displays the exchange conditions set by the exchange condition setting means 91 on the screen as shown in FIG. 7, for example.

  As described above, the exchange condition presenting means 53 of the present embodiment selects a player card that can be exchanged in advance from among the player cards owned by the player when determining the exchange condition. The exchange conditions are set later according to the selected player cards. In this case, as shown in FIG. 7, the CPU 1 of the game apparatus 100 presents to the player only the exchange conditions (exchange conditions consisting of the exchange condition items 1 to 3), and in order to set the exchange conditions in advance. The player card selected in the above is not requested to the player as a direct exchange condition. If the exchange conditions are determined in this way, there are certain player cards possessed by the player that surely satisfy the exchange conditions, so that smooth player card exchange can be realized.

  As a player, it is not always necessary to select a player card selected in advance by the CPU 1 for setting exchange conditions as an exchange target. That is, if the player owns another player card that satisfies the exchange condition, the other player card can be the target of exchange.

  Next, variations of the exchange condition presenting means 53 will be described with reference to the functional block diagram of FIG. The exchange condition presenting means 53 has a function of predicting a player card that the player does not want to exchange among player cards owned by the player and making the player card difficult to be included in the exchange condition. In order to realize this function, the exchange condition presenting means 53 shown in FIG. 5 further includes a team condition determining means 92 and a position condition determining means 93 in addition to the means 81 to 85 shown in FIG.

  Since the team specified by the above-mentioned team specifying means 66 is expected to be a player's favorite team, it can be predicted that the player does not want to be exchanged if he turns the other side. Therefore, the team condition determining means 92 has a function of determining the team conditions so that the team specified by the team specifying means 66 is selected with a lower probability than the other teams.

  The team condition determining unit 92 determines a team based on a random number generated by the random number generating unit 56, for example. Then, the team condition determining unit 92 sets the probability that the team specified by the team specifying unit 66 is selected when determining the team based on the random number, which is lower than the probability that the other teams are selected. For example, in the range (minimum value to maximum value) that can be acquired as a random number value, the random number value for which the team specified by the team specifying means 66 is selected is 4% (11/275), and the other 11 teams Each of the random number values drawn is weighted so that the probability of the random number lottery is about 8.73% (24/275), which is higher than that.

  The weighting of the lottery probability is not limited to the above example, and any lottery may be performed as long as the probability that the team specified by the team specifying means 66 is selected is lower than the probability that each other team is selected. Can be a probability.

  Further, since the shortage position specified by the above shortage position specifying means 69 is a position where the strength is insufficient as compared with other positions, it can be predicted that the player does not want to be exchanged. Therefore, the position condition determining unit 93 has a function of determining the position condition so that the insufficient position specified by the insufficient position specifying unit 69 is selected with a lower probability than other positions.

  The position condition determining unit 93 determines a team based on a random number generated by the random number generating unit 56, for example. Then, the position condition determining means 93 sets the probability that an insufficient position is selected when determining a team based on a random number lower than the probability that other positions are selected. For example, within a range that can be acquired as a random number value, the random value from which the insufficient positions are drawn is 10% (4/40), and the random values from which the other four positions are drawn are higher than that. The probability of random lottery is weighted so as to be 22.5% (9/40).

  The weighting of the lottery probability is not limited to the above example, and any lottery probability can be used as long as the probability that an insufficient position is selected is lower than the probability that other positions are selected.

  The exchange target selection means 83 shown in FIG. 5 is the position determined by the team condition determining means 92 and the position determined by the position condition determining means 93, and the “change to exchange” set by the strength setting means 82 described above. A player card that matches the necessary strength of each player card is selected from the player cards owned by the player. As a result, the player cards selected by the exchange target selection means 83 are the teams and positions that are expected not to be exchanged for the players (the teams and positions that are selected with a lower probability than the other teams and positions). ) Is reflected.

  And since the exchange condition determination means 84 determines an exchange condition based on the player card selected by the exchange object selection means 83, even if the exchange condition regarding the baseball team is presented as an exchange condition as a result. The probability that the team specified by the team specifying means 66 (the team that is expected to be the player's preference) is presented as a condition is lower than the probability that the other teams are presented as a condition. Similarly, even when the exchange condition related to the position is presented as the exchange condition, the probability that the insufficient position specified by the insufficient position specifying means 69 is condition-presented is higher than the probability that the other positions are presented as conditions. Also lower.

  When a team or position that a player does not want to be exchanged is presented as an exchange condition for the player, the exchange condition is usually not met. It is desirable to reduce the frequency of being performed. As described above, the exchange condition presenting means 53 shown in FIG. 5 determines the exchange condition, and the player's card team or position that he / she does not want to exchange among the player cards owned by the player. Therefore, it is difficult for the player card to be included in the exchange conditions, so that a smooth player card exchange can be realized.

  Next, as another variation of the exchange condition presenting means 53, it is expected that the exchange object selecting means 83 is not intended for exchange by the player without using the team condition determining means 92 and the position condition determining means 93. The configuration for selecting player cards in consideration of the team and position will be described. The basic configuration of the exchange condition presenting means 53 is the same as that in FIG. 4, but the operation of the exchange target selecting means 83 is different as follows.

  The exchange target selection means 83 selects a player card that matches the “strength of each player card necessary for exchange” set by the strength setting means 82 from player cards owned by the player. In addition, instead of randomly selecting a player card that matches the strength, the probability that a player card belonging to the team specified by the team specifying means 66 will be selected is determined by the player card belonging to each other team. Lower than the probability of being elected.

For example, among the player cards owned by the player, there are a total of n player cards (n is a positive integer of 2 or more) that match the strength set by the strength setting means 82, and these n cards It is assumed that m player cards belonging to the team specified by the team specifying means 66 are included in the player cards (m is a positive integer). In this case, if one player is randomly selected from n player cards, the selection probability of each player card is PS (%).
PS = (1 / n) × 100 = 100 / n (1)
It becomes the same selection probability of any player card. Therefore, if the selection probability of each player card belonging to the team specified by the team specifying means 66 is PV (%), in order to make this PX (%) lower than the random selection probability PS (%), For example,
PV = (100 / n) × (1 / a) (2)
(Where a is a coefficient). In this case, if the selection probability of each player card other than the team specified by the team specifying means 66 is PW (%),
PW = (100−PV × m) / (nm) (3)
Can be calculated as

  As a specific example, n = 10 (card) player cards that match the strength set by the strength setting means 82 exist among the player cards owned by the player. It is assumed that m = 2 (sheets) of player cards belonging to the team specified by the team specifying means 66 are included. When the coefficient a = 2, the random selection probability PS = 10 (%), the selection probability PV of each player card belonging to the team (the team expected to be the player's preference) identified by the team identification means 66 = 5 (%), the selection probability PW = 11.25 (%) of each player card belonging to another team. Thus, PV <PW, and each player card belonging to the team that is expected to be the player's preference is less likely to be selected by the replacement selection means 83 than each player card of the other team.

  Similarly, there are n player cards (n is a positive integer of 2 or more) that match the strength set by the strength setting means 82 among the player cards owned by the player. Assume that m player cards (m is a positive integer) are included in the player cards in the insufficient position specified by the insufficient position specifying means 69. Also in this case, the above formula (2) and the above formula (3) can be used. That is, the selection probability of each player card in the insufficient position can be calculated as PV (%) in the above equation (2). In addition, the selection probability of each player card for other positions can be calculated as PW (%) in the above equation (3).

Further, among the player cards owned by the player, there are a total of n player cards (n is a positive integer of 2 or more) that match the strength set by the strength setting means 82, and these n cards The player cards belonging to the team specified by the team specifying means 66 and the player cards of the insufficient positions specified by the insufficient position specifying means 69 are mixed in the player cards. At this time, there are p player cards X (p is a positive integer) that belong to the team specified by the team specifying means 66 and are also in an insufficient position, and the selection probability of each player card X is PX (%). To do. Further, there are q player cards Y (q is a positive integer) that belong to the team specified by the team specifying means 66 but are not in a short position, and the selection probability of each player card Y is PY (%). . In addition, there are r player cards Z (r is a positive integer) that are not positions but are not specified by the team specifying means 66, and the selection probability of each player card Z is PZ (%). Further, there are (n−p−q−r) player cards E that are neither the base team specified by the base team specifying means 66 nor the insufficient positions, and the selection probability of each player card E is set to PE (%). At this time, each selection probability is
PX = (100 / n) × (1 / a) × (1 / b) (4)
PY = (100 / n) × (1 / a) (5)
PZ = (100 / n) × (1 / b) (6)
PE = (100−PX × p−PY × q−PZ × r) / (n−p−q−r) (7) (where a and b in each equation are coefficients) be able to.

  As a specific example, when n = 10 (sheets), p = 1 (sheets), q = 1 (sheets), r = 2 (sheets), and coefficient a = b = 2, PX = 2.5 ( %), PY = 5 (%), PZ = 5 (%), PE = 13.75 (%), and PX <PY = PZ <PE. That is, the player card X belonging to the team specified by the team specifying means 66 (the team expected to be the player's preference) and also in a shortage position is most difficult to be selected, and the team specified by the team specifying means 66 or The player card Y or Z in the insufficient position is not easily selected next, and the player card E that is neither the team specified by the team specifying means 66 nor the insufficient position is most easily selected.

  By the way, even if it is a team card specified by the team specifying means 66 or a player card of an insufficient position specified by the insufficient position specifying means 69, the player card is replaced by a player because the number of ☆ of the player card is low. You may want to make a (replacement target). Therefore, the exchange target selection means 83 is limited to the player's card having a predetermined number of ☆ or less, even if it is a baseball specified by the baseball specifying means 66 or a shortage position specified by the shortage position specifying means 69, You may make it choose at random with the same probability as a player card.

[Operation of game device]
In the above configuration, an example of the operation of the game device 100 according to the embodiment of the present invention will be described below with reference to the flowcharts of FIGS.

  When the start button of the baseball game is pressed in the game apparatus 1, the game program is loaded and stored in the RAM 5 from the recording medium 300 storing the game program or the memory 18. At this time, various basic game data necessary for executing the baseball game are also loaded from the recording medium 300 or the memory 18 into the RAM 5 and stored therein. Thereby, the game program and the basic game data are recognized by the CPU 1 of the game apparatus 100, and the game apparatus 100 operates under the control of the CPU 1 based on the game program.

  As described above, when the player executes the game mode in which the game team 100 first forms an original team and plays a game, a predetermined number of player cards are given to the player. At this time, the predetermined number of player cards to be given to the player is determined by the CPU 1 of the game apparatus 100 drawing lots from all player cards in the game. For example, the CPU 1 generates a random number, selects a player card based on the acquired random number value, and gives it to the player.

In the selection of the player card, the player card having a larger basic ability value of the player character (in this embodiment, the strength of the player character represented by the number ☆) is weighted so that the probability of selection is lower. .

  Also, when a player purchases a player card at a shop in the virtual game space, the CPU 1 of the game apparatus 100 selects a player card to be purchased by drawing from all player cards in the game. Also in this case, the probability that the player card with the larger basic ability value of the player character is selected becomes lower.

  Therefore, there may be a case where a player's favorite player card does not exist in the player card first given from the CPU 1 or the player card obtained by purchase. Therefore, the player can try to exchange the player card currently owned by the player and the exchangeable card presented by the CPU 1 by using the player card exchange function of the game apparatus 100.

  When the player attempts to exchange player cards, for example, a menu “trade center” displayed on an initial screen (home screen or menu screen) (not shown) of the game apparatus 100 is selected. Thereby, it is possible to enter a virtual trade center (a virtual space in which a player can exchange player cards with the CPU 1) managed by the game apparatus 100. The player basically enters the virtual trade center at any time from the initial screen. Hereinafter, an example of the player card exchange process after entering the trade center will be described with reference to the flowchart of FIG. 18 and the screen examples of FIGS.

  When entering the virtual trade center from the initial screen, the exchangeable card presentation process by the exchangeable card presentation means 51 is executed (S1). In this exchangeable card presenting process, based on the player card owned by the player, a player card that the player desires to exchange is predicted, and the exchangeable card reflecting the prediction is presented on the screen. Yes. A more detailed description of the exchangeable card presentation process will be described later. An example of the exchangeable card presentation screen displayed by this processing is shown in FIG.

  The screen example of FIG. 6 shows a state where there are six exchangeable cards 101 lined up as “currently exchangeable cards”, and three of them are displayed as a list. Further, by operating the controller 19 (see FIG. 1) to select the page movement button 110 or pressing a predetermined button on the controller 19, the remaining three replaceable cards 101 not currently displayed can be confirmed. It is like that.

  In addition, when the controller 104 is operated to move the cursor 104 to one of the replaceable cards 101 in the lineup, the player character information of the replaceable card 101 is displayed in the ability display area 102 and the team display area 103. It has become so. In the ability display area 102, the player name, spine number, strength (☆ number), dominant arm (right throw or left throw) of the player card 101 selected by the cursor 104, standing position at the bat (right strike or left strike) Strike), right-handed skill (meet ability when using the right pitcher), rank of left-handed skill (meet ability when using the left pitcher), rank of long hitting power, The rank of scouting power, rank of total defense power, etc. are displayed. In the example of FIG. 6, since the player card 101 of the player C is selected with the cursor 104, the player name “player C”, the spine number “53”, ☆ 74, left throw, left strike are displayed in the ability display area 102. The information of the player C, the first position E rank and the left position G rank, is displayed as the skill strike vs. right D rank, skill strike vs. left C rank, long strike strength A rank, running ability F rank, and overall defense strength.

  Further, by operating the controller 19 and selecting the page movement button 111 or 112, other ability parameters not displayed on the current page can be displayed in the ability display area 102. In the present embodiment, various abilities of each player character are divided into a plurality of blocks (for example, six blocks), and the abilities of each block can be confirmed by switching pages with the page movement buttons 111 or 112. It has become. In the screen example of FIG. 6, the ability block (representative ability of the player character) on the first page is displayed. In this embodiment, each item of the capability block that can be confirmed on the first page is also used as an exchange condition item.

  In the team display area 103, the name of the team to which the player character of the player card 101 selected by the cursor 104 belongs is displayed. In the example of FIG. 6, since the player card 101 of the player C is selected with the cursor 104, the name of the team “the team T 1” to which the player C belongs is displayed in the team display area 103. Thus, if the exchangeable card 101 lined up is selected with the cursor 104, the detailed player character information of the selected exchangeable card 101 can be confirmed on the screen, so whether the player has a card to be exchanged. It is possible to easily determine whether or not.

  In the exchangeable card presentation screen of FIG. 6, the player operates the controller 19 to move the cursor 104 and selects the card to be exchanged from the presented choices of the exchangeable character 101. In order to confirm this selection process, the player may operate the controller 19 to select the determination button 113 or press a predetermined button on the controller 19. Further, a return button 114 and a help button 115 are also displayed on the screen of FIG. If the return button 114 is selected, the initial screen of the game apparatus 100 can be returned. If the help button 115 is selected, the operation explanation on the screen can be confirmed.

  As described above, if the player selects a card that the player wants to exchange from among the exchangeable cards 101 presented by the CPU 1 (YES in S2), the exchange condition presenting means 53 displays the exchangeable card 101 selected by the player and the player. Exchange condition presenting processing for presenting on the screen the exchange conditions for exchanging the player cards owned is executed (S3). Details of this exchange condition presentation processing will be described later. An example of the exchange condition presentation screen displayed by this processing is shown in FIG.

  In the screen example of FIG. 7, the exchangeable card 101 (player C card) selected by the player is displayed at the top of the screen, and in the exchange condition display area 120 below, two cards for exchange with the player C card are displayed. Exchange conditions are displayed. That is, (1) the first exchange condition of “players with 65 or higher” and “players with T2 belonging to the team”, and (2) “players with T3 as the team with their own team” and “ball speed of 149 km / h or higher” and “ The second exchange condition “right pitcher” is presented on the screen by the exchange condition presentation means 53. In this case, in order to obtain the exchangeable card 101 of the player C by exchange, the player has one player card that satisfies the first exchange condition and one player card that satisfies the second exchange condition. It is necessary to select a total of two cards as exchange targets from among the player cards owned by the player.

  In the exchange condition display area 120 of the exchange condition presentation screen of FIG. 7, an exchange card set area 121 is provided, and the player selects a card that satisfies the exchange condition from the player cards owned by the player. Then, it is set in the exchange card setting area 121. In order to set a player card in the exchange card setting area 121, if an exchange condition is selected (in this example, either the first or the second exchange condition is selected) and the enter button 113 is pressed (S4) YES), the screen shifts to the army selection screen illustrated in FIG. 8 (S5). In addition, if the return button 114 is selected on the screen of FIG. 7, it is possible to return to the exchangeable card presentation screen of FIG. Further, a button 122 to be exchanged is also displayed on the screen of FIG. 7, which is a button that is used after the player card has been set, which will be described later.

  The army selection screen of FIG. 8 displays a second arm button 131 and a third arm button 132 for selecting a player card to be exchanged from either the second army or the third army, and the player selects one of these buttons. By selecting and pressing the enter button 113, the army can be selected. On this screen, the exchangeable card 101 selected by the player (here, the player C card) and the ability display area 102 and the team display area 103 indicating the ability and team of the player character are displayed. Information of the card 101 can be confirmed. Further, if the return button 114 is selected on the screen of FIG. 8, it is possible to return to the exchange condition presentation screen of FIG.

  In the arm selection screen of FIG. 8, when the army is selected by the player (YES in S6), the extraction means 54a is a player card owned by the player and is selected from the player cards belonging to the selected army. Then, a player card satisfying the exchange condition is extracted (S7). Then, a list of player cards belonging to the selected army is displayed in a display state in which the player cards that satisfy the exchange condition are distinguished from the player cards that do not satisfy the exchange card (S8).

  FIG. 9 shows an example of a player card list display screen when the second army is selected. In this screen example, a maximum of 12 player cards 141 owned by the player can be displayed in the player card display area 140 at the same time. Further, by operating the up and down scroll buttons 142 by the controller 19, a player card 141 that is not currently displayed can be displayed in the player card display area 140. In this screen example, the player card 141 that satisfies the replacement condition is displayed with a bright brightness and the card is displayed brightly, while the player card 141 that does not satisfy the replacement condition is in a state that cannot be selected due to grayout display. Yes.

  In the player card list display screen of FIG. 9, the player operates the controller 19 to move the cursor 104, so that the player can exchange objects from among the player cards 141 that are brightly displayed (that is, player cards that satisfy the exchange conditions). Select the card that becomes. In order to confirm this selection process, the player operates the controller 19 to select the determination button 113. If the return button 114 is selected on the screen shown in FIG. 9, it is possible to return to the army selection screen shown in FIG.

  When the player card 141 satisfying the exchange condition is selected by the player on the player card list display screen in FIG. 9 (YES in S9), the player card 141 displays the exchange condition as shown in the exchange condition presentation screen in FIG. It is set (displayed) in the exchange card set area 121 provided in the area 120.

  In the exchange condition presentation screen shown in FIG. 7 or FIG. 10, since two exchange conditions are presented, if all of these two exchange conditions are not achieved (NO in S10), the process returns to S4, and all of the exchange conditions are presented. A loop process that repeats S4 to S10 is performed until the replacement condition is achieved.

  When all the exchange conditions are achieved (YES in S10), that is, in the example of FIG. 10, the player operates the controller 19 with two player cards satisfying the exchange conditions set in the exchange card set area 121. When the button 122 to be exchanged is selected, the exchange execution means 55 includes the exchangeable card 101 (player C card in the example of FIG. 10) and the player card 141 (player L and player V in the example of FIG. 10). Exchange with the other card is established (S12). At this time, the exchange execution means 55 updates the stored contents of the possessed card storage means 44 to the contents after the exchange is established (S12).

  Moreover, when the exchange execution means 55 establishes the above exchange, for example, as shown in FIG. 11, one exchangeable card 101 (player C card presented by the CPU 1) and two player cards 141 are provided. An effect display for notifying the player of the fact that the exchange with the player (two cards of player L and player V) has been established is performed.

  After the card exchange is established as described above, for example, as shown in FIG. 12, a label 150 such as “Exchanged” (or “Exchanged”) is superimposed on the exchanged card on the exchangeable card presentation screen. indicate. The card with the label 150 can no longer be exchanged.

  Here, the determination / update cycle of the exchangeable card 101 lined up on the exchangeable card presentation screen shown in FIG. 6 or 12 will be described. In the present embodiment, as described above, when an original team is organized by a player card owned by a player and participates in a tournament, after the tournament ends (for example, the player first virtual The player card exchange means 50 determines (updates) the lineup of exchangeable cards when entering a typical trade center or immediately after the tournament ends. For example, every time one tournament ends, three exchangeable cards are determined at a time, and when the transition to the exchangeable card presentation screen is made, the three exchangeable cards are arranged in the lineup. An upper limit may be set for the maximum number of sheets to be lined up, and 9 sheets is the maximum in this embodiment. Since 3 exchangeable cards are lined up at the end of each tournament, the maximum number of 9 cards will be lined up when the 3 tournaments are over. The three exchangeable cards newly determined after the end of the tournament are lined up in place of the oldest three cards, so that the latest nine cards are always lined up.

  As described above, the exchanged card is labeled “Exchanged” 150 and cannot be exchanged. Since the player can enter the virtual trade center from the initial screen at any time, the card can be exchanged at any time. However, if the player exchanges all replaceable cards in the lineup, a new exchange is possible. Cards cannot be exchanged until possible cards are lined up. Thus, players who want to actively exchange cards actively participate in the tournament so that new exchangeable cards are lined up. That is, the card exchange function of the game apparatus 100 is also a motivation for the player to actively participate in the tournament.

  Note that the time (cycle) for determining / updating exchangeable cards to be lined up is not limited to the above. For example, when the player has played a predetermined number of games (for example, 3 to 5 games). The exchangeable cards to be lined up may be determined / updated. Further, the number of exchangeable cards determined / updated at a time is not limited to three, and may be one, or two or four or more.

  Next, the subroutine of the exchangeable card presentation process (S1) in the flowchart of FIG. 18 will be described with reference to the flowchart of FIG. In selecting a replaceable card presented by the CPU 1, first, the team determining unit 61 of the replaceable card presenting means 51 determines a team belonging to the replaceable card (S21). At this time, the team determining unit 61 predicts a player's favorite team and makes it easier to select the team more probably than other teams.

Further, the position determining unit 62 determines the position of the exchangeable card (S22). At this time, the position determination unit 62 identifies the insufficient position based on the player card owned by the player, and makes it easier to select the insufficient position more probably than each of the other positions. The strength determining unit 63 determines the strength (☆ number) of the replaceable card (S23). Details of the subroutines of S21 to S23 will be described later. In addition, the order in which each process of S21-S23 is performed is not limited to this, Any process may be performed first.

  Next, initialization is performed by substituting 0 into a variable i used for performing loop control in subsequent steps S25 to S28 (S24). Thereafter, the replaceable card selection means 64 is a player character that satisfies all the conditions of the team, position and strength determined in S21 to S23 from all player characters in the game managed by the character management means 30. Are randomly selected as exchangeable cards (S25).

  Next, the CPU 1 determines whether or not the player already owns the player card selected in S25 (S26). If the player already has the selected player card (YES in S26), the variable i is incremented (1 is added to i) (S27), and it is determined whether i has reached 5 (S28). If i = 5 is not satisfied, that is, if the selection of the player card in S25 is less than 5 (NO in S28), the process proceeds to S25 again, and a loop process is repeated that repeats S25 to S28.

  If it is determined that the player does not own the player card selected in S25 before the selection of the player card in S25 exceeds five times (NO in S26), the CPU 1 presents the player card. It is determined to line up as a possible card (S29). The determined exchangeable card is stored in the exchangeable card storage means 64a. In this way, the lineup is determined after confirming that the player card selected in S25 is not the same as the card owned by the player. Therefore, the player card already owned by the player is included in the lineup as a replaceable card. It is difficult to line up.

  On the other hand, if i = 5 in S28, that is, if the selected player cards are all cards owned by the player as a result of repeating the selection of the player cards in S25 five times, The player card selection is abandoned and the card selected for the fifth time is determined to be lined up as a replaceable card presented by the CPU 1 (S29).

Note that the number of times the card selection process is repeated is not limited to five, but may be four or less, or may be six or more, and may be determined in consideration of the processing load of the CPU 1 and the like.

  Next, it is determined whether or not a predetermined number of cards have been determined as exchangeable cards presented by the CPU 1 (S30). In the present embodiment, since the number of cards to be lined up at one time is three, if three cards have not been determined (NO in S30), the process proceeds to S21, and the processes in S21 to S30 described above are performed. Will be repeated. If three replaceable cards to be lined up are determined (YES in S30), the lineup is updated and the replaceable card is presented on the screen as shown in the screen example of FIG. 6 (S31).

  As mentioned above, if the lineup of three exchangeable cards is determined / updated at the end of one tournament, when entering the virtual trade center for the first time after the tournament ends. Only the processes of S21 to S30 described above are executed, and the replaceable card determined as the lineup is stored in the replaceable card storage unit 64a. Until the next lineup is updated, the exchangeable cards stored in the exchangeable card storage unit 64a are read to omit the processes in S21 to S30, and the read exchangeable cards are presented on the screen. Is possible. In addition, the processes of S21 to S30 described above are not performed when the virtual trade center is first entered after the tournament ends, but are performed when the tournament ends (immediately after the tournament ends). Is stored in the replaceable card storage means 64a, and when the player enters a virtual trade center, the replaceable cards lined up from the replaceable card storage means 64a are read out. You may make it show on a screen.

  Next, the subroutine of the team determination process (S21) in the flowchart of FIG. 19 will be described with reference to the flowchart of FIG. In this team determination process, first, the team identification means 66 determines that the team to which the player characters of the most player cards belong is the player's favorite team based on the player cards owned by the player. Analyze (expect) and specify the team (S41). Alternatively, it is also possible to specify the team that the team selected as the own team when the player forms the original team is expected to be the player's favorite team.

  After that, the team determining means 67 determines the probability that the specified team will be randomly selected so that the team specified by the team specifying means 66 can be selected more easily than the other teams. (S42). For example, the lottery probability of the specified team is set to 20%, and the probability that each of the other 11 teams is drawn is set to about 7.27%. Thereafter, a random number is generated by the random number generation means 56 (S43), and the base team determination means 67 determines the base of the exchangeable card based on the random number value obtained at this time (S44).

  As described above, in the present embodiment, the player's favorite team (desired team) is analyzed based on the player card owned by the player, rather than selecting the exchangeable card presented by the CPU 1 completely at random.・ Foreseeable and anticipated teams are selected more easily than other teams, and replaceable cards are determined. If a replaceable card is selected at random, the player's desired card may not be presented as a replaceable card. On the other hand, in this game apparatus 100, the player's favorite baseball team (desired baseball team) and the expected baseball team cards are easily presented as exchangeable cards, and the player may be dissatisfied with the card exchange. Smooth card exchange can be realized.

  Next, the subroutine of the position determination process (S22) in the flowchart of FIG. 19 will be described with reference to the flowchart of FIG. In this position determination process, first, the average strength calculation means 68 of the position determination unit 62 calculates the average number of player cards (average strength) for each position based on the player cards owned by the player. (S51). In this embodiment, (1) starting pitcher, (2) relay / restraining pitcher, (3) infielder, (4) outfielder, (5) average number of player cards for each of the five positions of the catcher Is calculated. Thereafter, the shortage position specifying means 69 specifies the position having the lowest average number of stars calculated by the average strength calculation means 68 as a shortage position (S52).

  After that, the position determination means 70 determines the probability that the shortage position is random lottery so that the shortage position specified by the shortage position specification means 69 is more easily selected than each other position. (S53). For example, the lottery probability of the insufficient position is set to 30%, and the probability that each of the other four positions is drawn is set to 17.5%. Thereafter, a random number is generated by the random number generation means 56 (S54), and the position determination means 70 determines the position of the exchangeable card based on the random number value obtained at this time (S55).

  Thus, in this embodiment, instead of selecting a replaceable card presented by the CPU 1 at random, the shortage position is analyzed based on the player card owned by the player, The player expects the position to be obtained through exchange. The predicted positions are selected more easily than other positions, and exchangeable cards are determined. Thereby, in this game device 100, since the card expected to be the player's desired position is easily presented as a replaceable card, smooth card exchange can be realized without the player being dissatisfied with the card exchange.

  Next, the subroutine of the strength determination process (S23) in the flowchart of FIG. 19 will be described with reference to the flowchart of FIG. In this strength determination process, first, the strength determination unit 63 acquires information on any of the tournaments in which the player participated, the player's rank, or the average strength of the player cards owned by the player (S61). Here, a case where the strength determination unit 63 acquires information on a tournament in which the player has participated will be described as an example.

  After that, the probability table selecting means 72 uses the strength determination probability table stored in the strength determination probability table storage means 71 (the probability table based on the progress (difficulty) of the tournament illustrated in FIG. A probability table corresponding to the tournament that participated is selected (S62). For example, if the tournament in which the player participated was Grand Prix 4, the strength of the exchangeable card is 5% for ☆ 10-24, 30% for ☆ 25-54, 50% for ☆ 55-79, ☆ 80- A probability table in which 99 is 15% is selected. Thereafter, a random number is generated by the random number generation means 56 (S63), and based on the random number value obtained at this time, the strength determination means 73 determines the ☆ number (☆ number range) which is the strength of the exchangeable card. (S64).

  As described above, in this embodiment, by assigning a probability table according to the progress (difficulty) of the tournament in which the player has participated, a reasonable number of exchangeable cards corresponding to the progress of the tournament is selected. It is easy.

  Next, the subroutine of the exchange condition presentation process (S3) in the flowchart of FIG. 18 will be described with reference to the flowchart of FIG. In determining the exchange condition suitable for the exchangeable card presented by the CPU 1, first, the necessary number determining means 81 of the exchange condition presenting means 53 determines the number (required number) of player cards necessary for exchange with the exchangeable card. (S71). At this time, the required number determining means 81 increases the probability that the required number of cards increases as the number of replaceable cards is larger. A more detailed description of the necessary card number determination process will be described later.

  Thereafter, the exchange condition presenting means 53 determines exchange conditions so as to meet the required number of cards (S72). A more detailed description of this exchange condition determination process will be described later. Thereafter, it is determined whether or not replacement conditions for the required number of cards have been determined (S73). In the case of NO in S73, the process proceeds to S72, and the processes of S72 and S73 are repeated until the exchange conditions for the required number of cards are determined. When the exchange conditions for the necessary number of cards are determined (YES in S73), the exchange condition presenting means 53 presents the exchange conditions for the determined necessary number of cards on the screen as shown in the screen example of FIG. (S74).

  Next, the subroutine of the necessary card number determination process (S71) in the flowchart of FIG. 23 will be described with reference to the flowchart of FIG. In the required card number determination process, first, the required number determination unit 81 acquires information on the number of ☆ which is the strength of the exchangeable card presented by the CPU 1 (S81).

  Thereafter, the probability table selection means 87 selects a probability table corresponding to the number of replaceable cards from the card number determination probability table (see FIG. 14) stored in the card number determination probability table storage means 86 (S82). ). For example, if the strength of the replaceable card is ☆ 74, the probability table that the required number of cards is 40%, 2 is 40%, and 3 is 20% from the card number determination probability table of FIG. Will be selected. The card number determination probability table applied here is set so that the probability that the number of player cards required for replacement increases as the strength of the replaceable card increases.

  Thereafter, random numbers are generated by the random number generation means 56 (S83). Then, the number determination means 88 applies the probability table selected in S82, and based on the random number value generated by the random number generation means 56, the number of player cards necessary for exchange with the exchangeable card presented by the CPU 1 Is determined (S84).

  Next, the subroutine of the exchange condition determination process (S72) in the flowchart of FIG. 23 will be described with reference to the flowchart of FIG. In this exchange condition determination processing, first, the strength setting means 82 acquires information on the strength (☆ number) of the exchangeable card presented by the CPU 1 (S91) and is necessary for exchange with the exchangeable card. Information on the number of player cards is acquired (S92). Then, the strength setting means 82 calculates the strength of the player card from the number of replaceable cards presented by the CPU 1 and the required number of cards, for example, according to the calculation rule shown in FIG. 15 (S93). For example, if the exchangeable card has a strength of 74 and the required number of cards is two, the player card strength calculation results are from 59 to 69.

  Thereafter, the exchange target selecting means 83 selects one player card that matches the number of ☆ calculated in S93 from the player cards owned by the player stored in the owned card storage means 44 (S94). If there are multiple matching player cards, one of them will be selected at random.

  Thereafter, the exchange condition item selection means 90 first randomly selects one of the three basic exchange conditions shown in FIG. 16 based on, for example, a random number (S95). Next, it is determined whether or not the ability trade is selected as the basic exchange condition (S96). Here, when ☆ number trade or team trade is selected as the basic exchange condition (NO in S96), as shown in FIG. 17, exchange condition item ID = 1 or ID = 2 is used as the first exchange condition item. It is determined. On the other hand, when the ability trade is selected as the basic exchange condition (YES in S96), the exchange condition item selection means 90 selects one of a plurality of exchange condition items included in the ability trade (S97). Is determined as the first replacement condition item. In this case, when the player card selected by the exchange target selection means 83 is a fielder, the exchange condition item selection means 90 is one of exchange condition items ID = 3 (common item) and ID = 4-7 (fielder exclusive item). For example, one exchange condition item is selected at random based on a random number. When the player card selected by the exchange target selection means 83 is a pitcher, the exchange condition item selection means 90 is selected from the exchange condition item ID = 3 (common item) and ID = 8-14 (fielder exclusive item). One exchange condition item is selected at random based on the random number.

  Whether to add another (second) exchange condition item as well as the first exchange condition item determined as described above is determined based on, for example, random numbers. If it is determined to add the second replacement condition item (YES in S98), the process proceeds to S95, and the processes in S95 to S98 are repeated. In the present embodiment, a maximum of three replacement condition items are determined by the loop processing of S95 to S98.

  When no other exchange condition item is added in S98 (NO in S98), that is, it is decided not to add another exchange condition item based on a random number, or three exchange condition items that are the upper limit are decided. If yes, the process proceeds to S99. In this S99, the exchange condition setting means 91 is such that the player card itself selected in S94 satisfies the exchange conditions consisting of one to three exchange condition items determined in the loop process of S95 to S98. Set exchange conditions.

  As the exchange condition determination process, in addition to the above-described process shown in the flowchart of FIG. 25, the exchange corresponding to the exchange is made based on the exchangeable card presented by the CPU 1 without selecting a player card that can be exchanged in advance. It is also possible to determine the conditions. However, the process of selecting a player card that can be exchanged in advance from among the player cards owned by the player as described above, and setting the exchange conditions later according to the selected player card is better. It is preferable because a player card possessed by the player can surely satisfy the exchange condition.

  Next, a player card selection process different from the player card selection process (S94) in the flowchart of FIG. 25 will be described with reference to the flowchart of FIG. In the player card selection process in S94, one player card that matches the number of stars calculated in S93 is randomly selected from the player cards owned by the player. On the other hand, in the player card selection process of FIG. 26, instead of randomly selecting a player card that matches the number ☆, the player expects a baseball team and a position that the player does not want to exchange, Makes it difficult to select player cards for teams and positions.

  Here, the team and position that the player does not want to be exchanged are expected to be the team specified in S41 of FIG. 20 and the insufficient position specified in S52 of FIG. Therefore, in the player card selection process, first, the probability that the team specified in S41 is drawn is reduced from the probability that other teams are drawn (S101). For example, the lottery probability of the teams is set to 4% for the teams specified in S41 and about 8.73% for the other teams. Thereafter, a random number is generated by the random number generation means 56 (S102), and a team is determined based on the random value acquired at this time (S103).

  In addition, the probability that the shortage position specified in S52 is lottery is made lower than the probability that other positions are lottery (S104). For example, the lottery probability of positions is set to 10% for insufficient positions and 22.5% for the other four positions. Thereafter, a random number is generated by the random number generation means 56 (S105), and a team is determined based on the random value acquired at this time (S106).

  Thereafter, a player card that matches the team determined in S103, the position determined in S106, and the number determined in S93 in FIG. 25 is selected from the player cards owned by the player (S107). ).

  In this way, in the player card selection process, by making it difficult for a player to select a team card and a position card that are expected not to be exchanged for the player, the team and position are requested as a replacement condition presented by the CPU 1. Therefore, smooth player card exchange can be realized.

[Other Embodiments]
In the above-described embodiment, an example in which a character owned by a player in a virtual space is managed as information in a card format in which the form of the character can be visually recognized, and character exchange is realized as card exchange is described. However, instead of the card format, the player-owned character itself (for example, a character represented by two-dimensional or three-dimensional computer graphics in the virtual game space) may be used as an exchange target.

  As a mode in which the player owns the character in the virtual space, a mode in which the character is given to the player from the CPU when the game program is executed, as in this embodiment, a virtual currency or points that can be used in the game It is not limited to the mode of purchasing and owning a character and the mode of exchanging and possessing characters. For example, when a predetermined condition is satisfied during a game, the CPU gives the character to the player. An aspect may be sufficient. For example, in a game in which a score is given for an attack or defense against an opponent during a game such as a sports game or a battle game, a character is given to the player when the score obtained by the player exceeds a predetermined value. It may be an embodiment. Further, in various games having a plurality of stages in the virtual space, when a predetermined stage is cleared without game over, a character may be given to the player.

  In the above-described embodiment, a baseball game has been described as an example, but the present invention can be applied to all games using characters owned by a player in a virtual space. That is, in this game device, instead of exchanging characters between players, the CPU of the game device determines a replaceable character based on the player-owned character, and presents the determined replaceable character and its exchange condition to the player from the CPU side. The present invention can be suitably applied to all games having the function of exchanging characters.

  In particular, the game device is characterized in that the CPU predicts a group (team or the like) or position desired by the player based on a character owned by the player, and the characters in the predicted group or position are easily presented as exchangeable characters. It has various functions. The group referred to here is not limited to a team or the like in a baseball game, but refers to an entire group including a plurality of characters. The character may not be a person but an animal or a fictitious creature (for example, a monster or a fairy). The concept of groups and positions also exists in the same manner as baseball games in various sports games such as soccer games, American football games, basketball games, and volleyball games. The present invention is suitably applied to such sports games in general. can do.

  Furthermore, the present invention can be suitably applied to games other than sports games such as battle games. For example, in a battle game where a group called a command team is formed to infiltrate and attack enemy territory, each character owned by the player is, for example, “actual combat unit”, “research and development group”, “food group” In a battle game such as “medical team”, “intelligence group”, etc., which is arranged in each position, there are the same group and position concepts as the sports game. Thus, the present invention can be suitably applied to all games in which the concept of group or position exists in the virtual space.

  In the above-described embodiment, a home video game machine used by connecting to a home television has been described as an example of a game device. However, the present invention is not limited to this example. In other words, a portable game-dedicated device with an integrated monitor, a smartphone / mobile phone / PHS capable of executing an application program, or a personal computer or tablet terminal that functions as a game device by executing a game program Similarly, the present invention can be applied.

  Various computer-readable game programs according to the present embodiment are used for hard disks, optical disks (CD-ROM, DVD-ROM, UMD, etc.), flexible disks, semiconductor memories, ROM cassettes, or home video game apparatuses. It is recorded on various computer-readable recording media such as cartridges, read out from the recording media, and executed by the CPU of the game apparatus. Further, the means for providing the game program to the game device is not limited to the recording medium described above, and can be performed via a communication network such as the Internet. For example, if the game program can be downloaded from the homepage provided by the company that manages the network game via the Internet, the game program may be downloaded from the homepage directly to the game device and executed.

Therefore, the game management device can analyze (predict) the character that the player desires to exchange and select a replaceable character, as in the game device 100 described above. It is possible to provide the player with a highly entertaining game that can realize smooth character exchange while suppressing such dissatisfaction.

  (A) As described above, the game management device according to the present embodiment accepts access from the terminal device of each player via the network, and a game about a game using the owned character owned by the player. A game management device for providing services to each player via the network, comprising: character storage means for storing the owned character in a storage device; and character exchange means for exchanging the owned character with another character. The character exchange means determines an exchangeable character exchangeable with the possessed character based on the owned character, and transmits the information for displaying the exchangeable character on the terminal device, thereby exchanging the exchangeable character. On the screen of the terminal device. And a character exchange condition for exchanging the exchangeable character and the possessed character presented by the exchangeable character presenting means, and transmitting information for displaying the character exchange condition on the terminal device. The exchange condition presenting means for presenting the character exchange condition on the screen of the terminal device and the character to be exchanged with the exchangeable character among the owned characters are selected and operated on the terminal device. The selection operation information receiving means for receiving the selection operation information from the terminal device, and when the possessed character that satisfies the character exchange condition presented by the exchange condition presentation means is selected and operated on the terminal device, the ownership An exchange between the character and the exchangeable character is established, and the character It includes a replacement execution means for updating the stored contents of the data storage means the contents after replacement establishment, the.

  (B) In the configuration of (A), the game is a group game including a plurality of the owned characters, and the replaceable character presenting means calculates an average value of the basic ability values of the owned characters within the group. An average value calculating means for each position, an insufficient position specifying means for specifying a position having the lowest average value calculated by the average value calculating means as an insufficient position, and an insufficient position specified by the insufficient position specifying means It is preferable that position determination means for determining a position so that the position is drawn with a higher probability than other positions, and the character at the position determined by the position determination means is presented on the screen as a replaceable character.

  (C) In the configuration of (B) above, the exchange condition presenting means presents the probability that the insufficient position specified by the insufficient position specifying means is presented as the character exchange condition as a condition for each other position. It is preferable to set it lower than the probability.

  (D) In any one of the configurations (A) to (C), the owned character belongs to one of a plurality of predetermined groups, and the replaceable character presenting means is the most Group determination means for identifying a group to which many of the owned characters belong, and group determination for determining a group so that the group identified by the belonging group identification means is selected with a higher probability than other groups It is preferable that a character belonging to the group determined by the group determination unit is presented on the screen of the terminal device as a replaceable character.

  (E) In the configuration of (D), the exchange condition presenting means presents the probability that the group identified by the belonging group identifying means is presented as the character exchange condition as a condition for each of the other groups. It is preferable to set it lower than the probability. Thereby, there exists an effect similar to said (5).

  (F) In any one of the configurations (A) to (E), the exchange condition presenting means has the possession necessary for exchange with the exchangeable character as the basic ability value of the exchangeable character increases. Necessary number determining means for determining the required number so that the required number of characters is increased, and the necessary number determined by the necessary number determining means is larger as the required number is replaced with the exchangeable character. A basic ability value setting means for setting a basic ability value of each possessed character low, and the terminal device has the required number of character exchange conditions determined based on the basic ability value set by the basic ability value setting means. The exchange execution means presents the necessary number of possession caps that satisfy all the character exchange conditions presented by the exchange condition presentation means. When Kuta is selectively operated by said terminal device, it is preferable to establish the exchange of possessing character of the required number and the replaceable character.

  (G) In any one of the configurations (A) to (F), the exchange condition presenting means selects an owned character to be exchanged with the replaceable character from the owned characters. An object selection means; and an exchange condition determination means for determining the character exchange condition so that the possessed character selected by the exchange object selection means satisfies the character exchange condition, and is determined by the exchange condition determination means. It is preferable to present the character exchange conditions on the screen of the terminal device.

  (H) In any one of the configurations (A) to (G) described above, the game management device extracts, from the owned characters, a character that satisfies the character exchange condition presented by the exchange condition presentation unit And an extraction display means for displaying on the screen of the terminal device, by distinguishing the owned character extracted by the extraction means from the owned character that does not satisfy the character exchange condition, by transmitting information to be displayed on the terminal device. It is preferable that a player who operates the terminal device selects a character to be exchanged with the exchangeable character from among the owned characters displayed by the extraction display unit.

  The game management device having the above-described configurations (A) to (H) has the same operational effects as the above-described game device 100 described with reference to FIGS.

  (1) A game device according to one aspect of the present invention is a game device that executes a game using a owned character owned by a player in a virtual space, and stores the owned character in a storage device. And a character exchange means for exchanging the owned character with another character, wherein the character exchange means determines (a) a replaceable character exchangeable with the owned character based on the owned character, A replaceable character presenting means for presenting the replaceable character on the screen; and (b) setting a character exchange condition for exchanging the replaceable character and the possessed character presented by the replaceable character presenting means. An exchange condition presenting means for presenting the character exchange condition on the screen; (c) An exchange target character selection means for causing the player to select a character to be exchanged with the exchangeable character from among the possessed characters; and (d) an owned character that satisfies the character exchange condition presented by the exchange condition presentation means. When the exchange target character selection means is selected, the exchange execution means for establishing the exchange between the owned character and the exchangeable character and updating the content stored in the character storage means to the content after the exchange is established. ing.

  According to this configuration, the owned characters owned by the player in the virtual space, for example, player characters such as pitchers and fielders in the baseball game, are stored and managed in the character storage means. And this game device is provided with the character exchange means, Players can exchange the exchangeable character and player's possession character which are shown from the game device side instead of exchanging characters. In this character exchange, the exchangeable character presenting means determines the exchangeable character to be presented from the game device side based on the character owned by the player, so that the CPU in the game device wants the player to exchange. Characters can be analyzed to determine replaceable characters. The replaceable character determined in this way is displayed on the screen and presented to the player. Further, a character exchange condition for exchanging the exchangeable character and the player's own character is set by the exchange condition presenting means, and the character exchange condition is also displayed on the screen and presented to the player.

  As described above, when the exchangeable characters and the exchange conditions are presented from the game device side, the player confirms them on the screen, and determines whether or not to exchange the presented exchangeable characters with the player's own characters. Will be considered. Here, when the player tries to exchange, the character to be exchanged is selected from the own owned characters by the exchange character selection means. At this time, when the player selects a possessed character that satisfies the character exchange condition presented by the game apparatus, the exchange execution means establishes an exchange between the owned character and the exchangeable character presented by the game apparatus. Then, the exchange execution means updates the stored content of the owned character in the character storage means to the content after the exchange is established.

  As described above, in the conventional exchange between players, when the other player does not have the character desired by the player, or even if the other player has it, it will not be the subject of exchange. However, it is difficult to obtain the desired character, and if such a situation continues, the player may be dissatisfied with the exchange between the players. On the other hand, in the present game device, the exchangeable character to be presented by the game device is determined based on the player's own character as described above, so that the character that the player desires to exchange can be analyzed (predicted) and exchanged. Characters can be selected, and smooth character exchange that suppresses dissatisfaction during exchange between conventional players can be realized.

  (2) In the configuration of (1), the game is a group game including a plurality of the owned characters, and the replaceable character presenting means calculates an average value of the basic ability values of the owned characters within the group. An average value calculating means for each position, an insufficient position specifying means for specifying a position having the lowest average value calculated by the average value calculating means as an insufficient position, and an insufficient position specified by the insufficient position specifying means Position determining means for determining a position so that a lottery is drawn with a higher probability than other positions, and the replaceable character presenting means uses the character at the position determined by the position determining means as a replaceable character. It is preferable to present it on the screen.

  According to this configuration, positions (for example, a starting pitcher, a relay / repressing pitcher, an infielder) in a group including a plurality of player-owned characters (for example, a baseball team formed by player characters owned by the player in a virtual space) , Outfielders, catchers, etc.). This shortage position is specified by calculating the average value of the basic ability values of the characters owned by the player for each position in the group by the average value calculation means, and selecting the position with the lowest calculated average value as the shortage position. This is realized by the specifying means specifying the shortage position. Here, the basic ability value represents the height of the basic ability of each character (for example, in the case of a baseball game, the pitcher ability and fielder ability of the player character), and the average value of the basic ability value is the highest. The low position is a position that is insufficient in terms of strength, and can be expected to be a position that the player desires to obtain through exchange.

  This shortage position is drawn at a higher probability than other positions when determining the position of the exchangeable character. In this way, in this game apparatus, a character that the player wants to exchange is predicted by specifying the insufficient position based on the player's possessed character, and the character at the insufficient position is replaceable with the character at other positions. It is easy to be presented on the screen. In short, processing is performed to provide options that can compensate for the weaknesses of the group of players. This realizes smooth character exchange that more effectively suppresses dissatisfaction during the exchange between conventional players.

  (3) In the configuration of (2) above, the exchange condition presenting means presents the probability that the insufficient position identified by the insufficient position identifying means is presented as the character exchange condition as a condition for other positions. It is preferable to set it lower than the probability.

  Here, since the shortage position is a position where the strength is insufficient compared to other positions, it can be analyzed (predicted) that the player does not want to be exchanged. When a position that a player does not want to be exchanged is presented as an exchange condition, it is difficult to respond to the exchange condition. Therefore, the frequency with which such an exchange condition is presented from the game device may be reduced. desirable. Therefore, the game device sets the probability that the insufficient position is presented as the condition for character exchange by setting the probability lower than the probability that the other positions are presented as a condition, thereby making it difficult to present the insufficient position as the character exchange condition. Thus, smooth character exchange is realized.

  (4) In any one of the constitutions (1) to (3), the owned character belongs to any one of a plurality of predetermined groups, and the replaceable character presenting means is the most Group determination means for identifying a group to which many of the owned characters belong, and group determination for determining a group so that the group identified by the belonging group identification means is selected with a higher probability than other groups It is preferable that the replaceable character presenting means presents the characters belonging to the group determined by the group determining means on the screen as replaceable characters.

  According to this configuration, each character owned by the player belongs to one of a plurality of predetermined groups. For example, in a baseball game, a plurality of teams corresponding to 12 professional Japanese baseball teams in the real world also exist in the virtual space as a group, and each character belongs to one of these teams. The group having the largest number of groups to which the player's owned characters belong is specified by the belonging group specifying means. The group specified in this way can be expected to be a favorite group that the player actively collects, that is, a group to which the player wants to obtain by exchange.

  The group specified by the belonging group specifying means is selected with a higher probability than other groups when determining the belonging group of the exchangeable character. In this way, in this game apparatus, a player's favorite group is predicted based on the player's possessed characters, and the characters of the group are more easily presented on the screen as exchangeable characters than the characters of other groups. Thus, smooth character exchange that more effectively suppresses dissatisfaction during the exchange between conventional players is realized.

  (5) In the configuration of (4), the exchange condition presenting means has a probability that the group specified by the belonging group specifying means is condition-presented as the character exchange condition, and the probability that other groups are condition-presented. It is preferable to set a lower value.

  Here, since the group specified by the belonging group specifying means is expected to be a favorite group of the player as described above, it is a group that the player thinks that the player does not want to be exchanged if he turns it back. It can be analyzed (predicted). When a group that a player does not want to be exchanged is presented as an exchange condition for a player, it is difficult to respond to the exchange condition. Therefore, the frequency with which such an exchange condition is presented from the game device may be reduced. desirable. Therefore, the game apparatus sets the specified group by setting the probability that the group specified by the belonging group specifying means is condition-presented as a character exchange condition lower than the probability that other groups are condition-presented. Is difficult to be presented as a character exchange condition, thereby realizing a smooth character exchange.

  (6) In any one of the above configurations (1) to (5), the exchange condition presenting means increases the basic ability value of the exchangeable character, and the possession necessary for exchange with the exchangeable character Necessary number determining means for determining the required number so that the required number of characters is increased, and the necessary number determined by the necessary number determining means is larger as the required number is replaced with the exchangeable character. Basic ability value setting means for setting the basic ability value of each possessed character low, and the necessary number of character exchange conditions determined based on the basic ability value set by the basic ability value setting means are displayed on the screen. The exchange execution means presents the necessary number of owned characters satisfying all the character exchange conditions presented by the exchange condition presentation means. When selected by the character selecting means, it is preferable to establish the exchange of possessing character of the required number and the replaceable character.

  According to this configuration, the necessary number determining means is a player-owned character required for exchange with the higher the basic ability value of the exchangeable character that is presented from the game device side and that the player will consider as an exchange target. The probability that the required number becomes large is increased so that the necessary number tends to increase. At the same time, in consideration of the balance between the necessary number required for exchange and the basic ability value, the basic ability value setting means increases the required number of player-owned characters necessary for exchange, The basic ability value of the owned character is set low. The exchange condition presenting means presents the same number of character exchange conditions as the necessary number determined in this way on the screen, and the exchange execution means provides the necessary number of owned characters satisfying the character exchange condition to be exchanged. As a result, the exchange is established.

  Thereby, when a replaceable character having a relatively high basic ability value is presented from the game device side, the required number of owned characters of the player necessary for exchange is increased, and the basic ability value of each owned character is decreased. It is set to become. Therefore, even if the player does not own a character with a high basic ability value suitable for a replaceable card, or even if you own a character with such a basic ability value, By exchanging “one-to-many” with a plurality of owned characters having a lower basic ability value as an exchange target, the character exchange is easily established, and smooth character exchange is realized.

  (7) In any one of the constitutions (1) to (6), the exchange condition presenting means selects an owned character to be exchanged with the replaceable character from the owned characters. An object selection means; and an exchange condition determination means for determining the character exchange condition so that the possessed character selected by the exchange object selection means satisfies the character exchange condition, and is determined by the exchange condition determination means. It is preferable to present the character exchange conditions on the screen.

  According to this configuration, when determining the character exchange condition, the owned character that can be exchanged in advance is selected from the owned characters of the player by the exchange target selecting means. Then, the exchange condition determining means is configured to determine the character exchange condition later according to the owned character selected in advance. If the character exchange conditions are determined in this way, there is a character that satisfies the character exchange condition reliably among the characters owned by the player, so that smooth character exchange can be realized.

  (8) In any one of the constitutions (1) to (7), the exchange target character selecting means selects a character satisfying the character exchange condition presented by the exchange condition presenting means from the owned characters. Extracting means for extracting, and extraction display means for displaying on the screen the owned character extracted by the extracting means in distinction from owned characters that do not satisfy the character exchange condition, the exchange target character selecting means, It is preferable that the player selects a character to be exchanged with the exchangeable character from among the owned characters displayed by the extraction display means.

  According to this configuration, when the exchange target character selection means displays a list of characters owned by the player on the screen and allows the player to select a character to be exchanged from among the characters, the extraction means selects from the player owned characters. Characters satisfying the character exchange condition are extracted, and the extraction display means distinguishes and displays the owned characters that do not satisfy the exchange conditions and the owned characters that do not satisfy the exchange conditions (for example, display states with different brightness, color, size, etc.) And). Thus, even when there are a large number of owned characters of the player, the player can easily find the owned characters satisfying the character exchange condition from the list display screen, and the operation of selecting the owned character to be exchanged can be performed accurately and smoothly. It can be carried out.

  (9) A game control method according to another aspect of the present invention is a game control method in which a computer controls a game using a owned character owned by a player in a virtual space, and the computer controls the owned character. A character storing step for storing in a storage device; and a character exchanging step for exchanging the owned character with another character by the computer.

An exchange target character selection step for causing the player to select a character; and (d) when an owned character that satisfies the character exchange condition presented in the exchange condition presentation step is selected in the exchange target character selection step, the computer An exchange execution step of establishing an exchange between the character and the exchangeable character and updating the storage content of the storage device to the content after the exchange is established.

  (10) A program according to yet another aspect of the present invention is a program for causing a computer to operate as the game device, and for causing the computer to function as each means included in the game device. It is.

  (11) A game management device according to still another aspect of the present invention receives a game service for a game using a possessed character owned by a player in response to access from the terminal device of each player via a network. A game management device provided to each player via the network, comprising: character storage means for storing the owned character in a storage device; and character exchange means for exchanging the owned character with another character. The exchange means determines the exchangeable character exchangeable with the possessed character based on the possessed character, and transmits the information for displaying the exchangeable character on the terminal device, thereby replacing the exchangeable character with the terminal. Interchangeable character presenter presenting on device screen A character exchange condition for exchanging the exchangeable character and the possessed character presented by the exchangeable character presenting means, and transmitting information for displaying the character exchange condition on the terminal device The exchange condition presenting means for presenting the character exchange condition on the screen of the terminal device, and the character to be exchanged with the exchangeable character among the possessed characters is selected and operated on the terminal device The selection operation information receiving means for receiving the selection operation information from the terminal device, and when the possessed character that satisfies the character exchange condition presented by the exchange condition presentation means is selected and operated on the terminal device, the possessed character And the exchangeable character is established, and the character And replacement execution means for updating the stored contents of 憶 means the contents after replacement satisfied, and a.
