DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of games in which a player can freely set a battle start condition in progress.

[0002]

2. Description of the Related Art Recently, as one field in computer games and video games, RPG (Role Playi
ng Game) is known. The RPG is given by a character operated by a player (hereinafter, own character) growing and growing through various events unfolded in a virtual world in a game, such as a battle with an opponent character (hereinafter, enemy character). It generally refers to games with narratives such as unraveling mysteries and secrets toward the final goal.

[0003]

2. Description of the Related Art In conventional RGB, a player operates his own character and moves it to a destination set in a field in a virtual world. At that time, the player battles with an enemy character that is encountered at a predetermined ratio and defeats the enemy character, thereby acquiring experience value and money. The own character grows when the set level is improved (hereinafter, “level-up”) according to the accumulated value of the acquired experience values, and the predetermined ability value is increased accordingly.

A plurality of such ability values are usually set for the own character, and have a predetermined role in a battle with an enemy character. For example, "HP (Hit Point)" and "MP (Magic Poin
t) ”,“ power ”,“ magic power ”,“ physical strength ”,“ mental strength ”, and“ quickness ”are set, and in the battle with the enemy character, each ability value is as shown below. Play various roles.

[0005] "HP" represents the remaining life of the own character, and decreases by a predetermined value each time an attack is made from an enemy character. At this time, if "HP" becomes "0", the own character has been defeated, and the game ends. "M
“P” indicates the remaining magic usage of the own character, and is reduced by a predetermined amount of consumption every time an attack magic or the like is used for an enemy character. When “MP” decreases and becomes a value equal to or less than the magic consumption, the own character cannot use the magic.

[0006] "Power" represents the attack power using a weapon,
The larger the value, the greater the damage to the enemy character. “Magic power” represents the power of magic, and the greater the value, the greater the damage to the enemy character due to attack magic or the like. “Physical strength” represents the resistance to damage received by the own character when attacked by an enemy character with a weapon, and the greater the value, the smaller the damage received by the own character.

[0007] "Mental power" represents the resistance to damage received by the own character when the enemy character is attacked by magic, and the greater the value, the smaller the damage received by the own character. The “quickness” indicates the agility of the movement, and the larger the value, the easier it is to escape from the battle with the enemy character, or the easier it is to get an opportunity to attack earlier than the enemy character.

Such an ability value can be increased not only by the experience value that can be obtained by defeating the enemy character, but also by equipping weapons such as weapons and armor purchased with the obtained money. .

In the RPG, places where such weapons can be purchased appear as shops such as weapon shops and armor shops in towns set at predetermined positions in the field. In general, a plurality of towns are set in the field, and the weapons sold to the shops differ for each town. The more effective the armor, the more sold it is to the town set near the destination,
The price is also high. That is, the player needs to save money obtained by defeating many enemy characters and purchase expensive armor.

The amount of money obtained by defeating an enemy character differs depending on the type of the enemy character. In general, as the character defeats a strong enemy character (an enemy character with a high ability value), the amount of money that can be acquired increases. Such a strong enemy character is set to be encountered only when the player character moves to the vicinity of the destination in the field. Therefore, in order to earn money efficiently, the player needs to bring his or her own character close to the destination, fight with the enemy character, and win.

[0011]

However, such R
In the PG, since the encounter probability, which is the ratio of encountering the enemy character, is determined in advance, the battle starts only at a predetermined ratio during the movement of the own character regardless of the growth process of the own character or the player's intention. . For example, if your character's growth is low and you want to encounter an enemy character to grow your character,
Since the player's own character has a high growth, even if the player does not want to encounter an enemy character in order to advance the story, the battle is started only at a predetermined ratio.

[0012] For this reason, a player who has a desire to encounter an enemy character feels that time is wasted if he does not encounter an enemy character even if he moves his or her own character in the field vertically and horizontally. I get stress. On the other hand, a player who has a feeling that he / she does not want to encounter an enemy character feels annoyed when encountering an enemy character even if the player moves his / her character straight toward the destination. Embrace the stress of

In order to prevent the player from feeling wasted time and annoyance, there is a game in which predetermined items are used to make it difficult to encounter an enemy character or to make it easier to encounter. However, the effect becomes invalid after a certain period of time, so that it is necessary to constantly use a predetermined item in order to maintain the effect.

[0014]

Hereinafter, variable data and the like read from the CD-ROM 3 by the CPU 101 and stored in the main memory 104 to implement the game in the present embodiment will be described with reference to the drawings.

The main memory 104 has a program area, a field data area, a character data area, a variable table area, and the like, as shown in FIG. The CPU 101 stores a CD-ROM 3 in each area.
-A program, field data, character data, and a variable table read via the ROM buffer 115 are stored.

First, the field data area shown in FIG. 3 will be described. The field data area includes image data of a field in a predetermined virtual world as shown in FIG. 4 and a movable range for each of four divided areas in the feed as shown in FIG.
It has a field table that includes the position of the destination, the position of the rest area, and the hiding position.

The movable range shown in FIG. 5 corresponds to the land 2 in FIG.
1, which indicates a range in which the own character can move in each area.

The positions of the destinations correspond to the bridges 22 to 24 and the tower 25 in FIG. 4, and represent the positions set in advance as the destinations in each area. When the own character operated by the player moves to this position, a predetermined event or the like along the story starts. For example, an enemy character that is the leader of the area is set at each destination, and when the own character moves to each position, the enemy character that is the leader is always encountered, and the battle starts. Therefore, the own character operated by the player cannot move to another area unless the enemy character which is the leader is defeated by the battle. It is assumed that the strength of the enemy character that is the leader set as the destination increases stepwise from the first area to the fourth area.

The positions of the rest areas correspond to the towns 26 to 29 in FIG. 4, and represent positions set so that the HP of the own character can be recovered in each area and the weapons can be purchased. It is assumed that the weapons that can be purchased at the rest area gradually increase the effects such as offensive power and defensive power and the purchase price in the order from the first area to the fourth area.

The latent positions represent a plurality of predetermined positions where the enemy character is lurking. When the own character moves to these positions, an encounter is determined according to an encounter probability described later, and it is determined whether or not the own character has encountered an enemy character.

Returning to FIG. 3, the character data area is
It has image data of characters including the own character and the enemy character, and setting data of each character. The setting data includes an enemy character setting table as shown in FIG.

In the enemy character setting table shown in FIG. 6, the HP, acquisition experience value, and acquisition amount of each enemy character are set. HP represents the life value of the enemy character. The acquired experience value and the acquired amount represent the experience value and the amount that the own character can acquire when the enemy character is defeated. As shown in FIG. 6, different enemy characters are associated with each area in advance, and each enemy character corresponding to the area has an HP, an acquired experience value, and an acquired amount in a stepwise order from the first area to the fourth area. Set to increase.

Returning to FIG. 3, the variable table area is
FIG. 7A shows an encounter information table including the probability of encounter with an enemy character, and FIG. 7B shows an enemy character selection table including the HP, the acquired experience value, and the acquired amount of money of the selected enemy character. There is an own character state table including the own character's position, HP, accumulated experience value, and accumulated amount shown in c).

The encounter probability in the table shown in FIG.
When the player's character reaches the hiding position of the enemy character while moving through the field by the operation of the player, the ratio of encountering the enemy character is a value determined for each enemy character. The encounter probability is expressed as a percentage. When the encounter probability is 100, when the own character moves to the encounter position in the preset field, it always encounters the enemy character. On the other hand, when the encounter probability is 0, Even when the player character moves to the encounter position, the player character does not encounter the enemy character.

For example, as shown in FIG. 7A, when different encounter probabilities are set for the enemy characters (enemy 11 to enemy 14) in the first area, when the own character moves to the hidden position. Then, he encounters the enemy 11 with a probability of 1/2, encounters the enemy 12 with a probability of 3/4, and always encounters the enemy 14 without encountering the enemy 13. The probability of encountering each enemy character is determined at the start of the game.
All are set to 50, but can be changed as appropriate by the encounter probability setting process described later.

The enemy character selection table shown in FIG. 7B shows the enemy character selected according to the encounter probability shown in FIG. 7A and various information set for the selected enemy character in FIG. And a value obtained from the character setting table. HP shown in FIG. 7 (b)
Represents the remaining life of the enemy character, and decreases by a predetermined value each time the enemy character is attacked. At that time, HP
Becomes "0", the enemy character is defeated. The acquired experience value and the acquired amount represent the experience value and the amount that the own character can acquire when the enemy character is defeated.

The own character state table shown in FIG. 7C shows various states of the own character. The position in FIG. 7C represents the current position in the field of the own character operated by the player. HP represents the remaining life of the own character, and decreases by a predetermined value each time an attack is made from an enemy character. At this time, if the HP becomes "0", the own character is defeated, and the game ends. The accumulated experience value and the accumulated amount represent the accumulated value of the experience value and the amount acquired when the own character defeats the enemy character.

Hereinafter, an RPG that can freely set the probability of encountering an enemy character operating in the home game machine 1 will be described.

In the following description, the processing executed by the CPU 101 includes a coprocessor or a sub-processor other than the CPU 101 (GTE 102, GPU 10
9, SPU 111). In addition, various data stored in the CD-ROM 3 are actually sequentially read out from the CD-ROM 3 under the control of the CPU 101 in accordance with the progress of the processing.
After being decompressed by the EC 106, it is transferred to the main memory 104. In the following description, a detailed description of reading, decompression, and transfer of the processing program from the CD-ROM 3 to the main memory 104 is omitted. In addition, in order to facilitate understanding, processing related to audio output is omitted.

When playing the game, the player operates the open button 12 to open the disc holder 11 and
After setting the ROM 3 in the CD-ROM drive 113 of the consumer game machine 1, the disc holder 11 is closed.
In this state, when the player presses the power button 13 or presses the reset button 14 while the power is on, the processing of the main routine shown in FIG. 8 is started.

In the processing of the main routine, the CPU 101
First, execute the program for the opening process,
The opening video and audio are output from the television receiver 2 (step S101). The CPU 101
In this state, it is determined whether or not there has been an input from the start button of the controller 116 (step S102).

When it is determined in step S102 that there is no input from the start button (step S10
2; No), the CPU 101 executes steps S101 and S1.
02 is repeated, the opening video and audio are continuously output from the television receiver 2, and the input of the start button is awaited.

On the other hand, if it is determined in step S102 that there has been an input from the start button (step S1).
02; Yes), the CPU 101 sets the start screen in FIG.
Is displayed on the television receiver 2 (step S103). Note that the background image shown in FIG. 9 is a terrain in which a part of the field shown in FIG.

The CPU 101 operates as follows:
It is determined whether or not the button has been pressed (step S10).
4). That is, the CPU 101 determines whether or not the △ button for instructing the start of the encounter probability setting process has been pressed.

When the CPU 101 determines that the button has been pressed (step S104; Yes), the CPU 101 performs an encounter probability setting process (step S105). In the encounter probability setting process, the CPU 101 changes the value of the encounter probability table shown in FIG. The details of the encounter probability setting process will be described later.

After the encounter probability setting process or when it is determined that the △ button has not been pressed (step S104;
No), the CPU 101 determines whether or not the direction key of the controller 116 has been pressed (step S10).
6). That is, the CPU 101 determines whether the direction key for instructing the movement of the own character has been pressed.

If it is determined that the direction key has not been pressed (step S106; No), the CPU 101 returns the processing to step S104, and returns to steps S104 to S104.
The process of S106 is repeated.

On the other hand, if it is determined that the direction key has been pressed (step S106; Yes), the CPU 101 moves the position of the own character according to the pressed direction key (step S107). That is, CPU1
01 moves the position of the own character by a predetermined value in the direction of the pressed direction key, and updates the position of the own character shown in FIG. 7C. Note that the CPU 101
Does not change the position of the player character if the destination position is not within the movable range shown in FIG.

When the position of the own character is moved, the CPU 101 performs an encounter determination process (step S108).
That is, the CPU 101 determines the position of the own character,
In accordance with the latent position shown in FIG. 7 and the encounter probability shown in FIG. 7A, an encounter determination process is performed to determine whether or not an enemy character has been encountered. The details of the encounter determination process will be described later.

The CPU 101 determines whether or not an enemy character has been encountered by the encounter determination processing (step S1).
09). That is, the CPU 101 determines whether or not one or more enemy characters are selected in the enemy character selection table set by the encounter determination processing.

If it is determined that no enemy character has been encountered (step S109; No), the CPU 101 returns the process to step S104, and returns to step S104.
To S109 are repeated.

On the other hand, if it is determined that an enemy character has been encountered (step S109; Yes), the CPU 101
A battle process is performed (step S110). That is, CP
U101 performs a battle process in which the enemy character selected by the encounter determination process and the own character fight. The details of the battle process will be described later.

After the battle process, the CPU 101 determines whether the HP of the own character is 0 (step S111).
That is, the CPU 101 determines whether or not the end of the battle process is due to the HP of the own character being set to 0.

If it is determined that the HP of the own character is 0 (step S111; Yes), the CPU 101
An end process such as displaying an end screen is performed (step S1).
12) End the game. On the other hand, the HP of the own character
Is not 0 (step S111; N
o), the CPU 101 returns the process to step S104, and repeats the processes of steps S104 to S111 described above.

Hereinafter, the encounter probability setting process in step S105 will be described with reference to the flowchart shown in FIG.

In the encounter probability setting process, first, the CPU
101 displays a status screen as shown in FIG. 11 on the television receiver 2, and prompts an input to the encounter probability setting (step S201). That is, a selection dialog 41 that includes the encounter probability setting as a selection item and a selection cursor 42 that can be moved up and down are displayed.

When the setting of the encounter probability is selected by the selection cursor 42, the CPU 101 causes the television receiver 2 to display an encounter probability setting screen as shown in FIG. 12 (step S202).

The CPU 101 operates as follows:
It is determined whether or not the button has been pressed (step S20).
3). That is, the CPU 101 determines whether the △ button for instructing the end of the encounter probability setting has been pressed.

If the CPU 101 determines that the button has been pressed (step S203; Yes), the CPU 101 proceeds to FIG.
The changed encounter probability is reflected in the encounter information table of (a), and the encounter information table is updated (step S21).
1). After updating the encounter information table, the CPU 101 ends the encounter probability setting process, and returns the process to step S106 in FIG.

On the other hand, if it is determined that the △ button has not been pressed (step S203; No), the CPU 101
Determines whether the direction key has been pressed (step S204). That is, the CPU 101 determines whether or not the direction key for instructing the vertical movement of the selection cursor 52 in the selection dialog 51 including the selection items representing each enemy character as a card shown in FIG. 12 is pressed.

If it is determined that the direction key has not been pressed (step S204; No), the CPU 101 returns the processing to step S203 and repeats the above processing.

On the other hand, if it is determined that the direction key has been pressed (step S204; Yes), the CPU 101 moves the selection cursor 52 in accordance with the pressed direction key (step S205), and determines the front and back of the card and the probability of encounter. It is displayed on the card display dialog 53 and the probability display dialog 56 (step S206). That is,
The CPU 101 displays the encounter probability in the encounter information table shown in FIG. 7A corresponding to the position of the moved selection cursor 52 in the probability display dialog 56, and displays the card front surface 54 and the card back surface 55 in the card display dialog 53. The ratio is displayed relative to the probability of encounter. Card front surface 54 and card back surface 5 displayed in card display dialog 53
In the ratio of 5, the display ratio of the card front surface 54 is equal to the value of the encounter probability, and the display ratio of the card back surface 55 is equal to 100 minus the encounter probability. For example, as shown in FIG. 12, when 50 is displayed in the probability display dialog 56, the ratio of the card front surface 54 and the card back surface 55 displayed in the card display dialog 53 is exactly the same.

The CPU 101 operates as follows:
It is determined whether or not the button has been pressed (step S20).
7). That is, the CPU 101 determines whether or not the ボ タ ン button instructing the selection of the enemy character displayed as the card where the selection cursor 52 is located has been pressed.

If it is determined that the ○ button has not been pressed (step S207; No), the CPU 101 returns the process to step S203, and returns to steps S203 to S203.
The process of S207 is repeated.

On the other hand, if it is determined that the ○ button has been pressed (step S207; Yes), the CPU 101
It is determined whether or not the button has been pressed (step S20).
8). That is, the CPU 101 determines whether or not the △ button for instructing the end of the change of the encounter probability of the selected enemy character has been pressed.

If it is determined that the △ button has been pressed (step S208; Yes), the CPU 101 returns the process to step S203, and returns to steps S203 to S2.
Step 08 is repeated.

On the other hand, if it is determined that the △ button has not been pressed (step S208; No), the CPU 101
Determines whether the direction key has been pressed (step S209). That is, the CPU 101 determines whether or not the direction key for instructing the increase or decrease of the actual value of the encounter probability of the selected enemy character has been pressed.

If it is determined that the direction key has not been pressed (step S209; No), the CPU 101 returns the processing to step S208 and repeats the above processing.

On the other hand, if it is determined that the direction key has been pressed (step S209; Yes), the value of the encounter probability that has been increased or decreased is displayed in the probability display dialog 56 according to the pressed direction key, and the card display dialog 53 is displayed. The card front surface 54 and the card back surface 55 are displayed in proportion to the changed probability of encounter (step S210).
For example, when the direction key (upward) is pressed and the encounter probability displayed in the probability display dialog 56 is changed from 50 to 51, the ratio of the card front surface 54 and the card back surface 55 displayed in the card display dialog 53 becomes 51 : Changed to 49.

As described above, the probability of encounter with each changed enemy character is determined in step S211 described above with reference to FIG.
Is reflected in the probability of encounter. As a result, the player can freely change and set the probability of encountering each enemy character. Further, since the probability of encountering each enemy character can be visually grasped as the ratio of the front and back of the card, even a young player who cannot understand the percentage can understand the meaning.

Hereinafter, the encounter determination processing in step S108 in FIG. 8 will be described with reference to the flowchart shown in FIG.

In the encounter determination processing, first, the CPU 10
1 clears the enemy character selection table (step S301). That is, the CPU 101 executes the process shown in FIG.
A predetermined initial value is set for all items in the enemy character selection table shown in FIG.

The CPU 101 determines whether or not the position to which the own character has moved is a latent position (step S30).
2). That is, the CPU 101 determines whether or not the position of the own character shown in FIG. 7C moved according to the operation of the player is equal to one of the latent positions in the area shown in FIG.

If it is determined that the position to which the own character has moved is not a hidden position (step S302; No), the CP
U101 ends the encounter determination processing, and returns the processing to step S109 shown in FIG.

On the other hand, when it is determined that the position to which the own character has moved is a latent position (step S302; Ye)
s), the CPU 101 acquires a target range in the encounter probability setting table (step S303). That is, the CPU 101 determines from the position of the self-character in FIG. 7A which of the four regions the self-character belongs to, and the CPU 101 in the encounter information table in FIG. Get the target range.

When the target range in the encounter information table is obtained, the CPU 101 obtains the probability of encountering one enemy character from the target range (step S30).
4). That is, the CPU 101 obtains the probability of encountering one enemy character according to a predetermined order in the target range of the encounter information table.

Further, the CPU 101 determines whether or not the encounter probability could not be obtained because the data to be obtained has been completed (step S305). That is, the CPU 10
1 determines whether or not the encounter probability of all enemy characters has been acquired in the target range of the encounter information table.

If it is determined that the encounter probability could not be obtained (step S305; Yes), the encounter determination processing is terminated, and the processing returns to step S109 shown in FIG.

On the other hand, when it is determined that the encounter probability has been acquired because the data to be acquired is not completed (step S305; No), the CPU 101 sets a reference value according to the acquired encounter probability (step S306). ). That is, the CPU 101 sets a reference value used to determine an encounter with an enemy character in accordance with the acquired encounter probability. For example, if the acquired encounter probability is 50,
The CPU 101 sets the reference value to 0.5.

After setting the reference value, the CPU 101 generates a random number (step S307). That is, CP
U101 randomly generates a numerical value within a predetermined range by using a random number. For example, CPU 101
Generates a value in the range of 0.0 to 1.0 by a random number.

The CPU 101 determines whether the value generated by the random number is equal to or smaller than the reference value set in step S307 (step S308).

If it is determined that the value generated by the random number is larger than the reference value (step S308; No), the CPU
The process returns to step S304, and the process of steps S304 to S308 is repeated.

On the other hand, when it is determined that the value generated by the random number is equal to or less than the reference value (step S308; Ye
s), the CPU 101 selects an enemy character (step S309). That is, the CPU 101 obtains various information corresponding to the enemy character in FIG. 7A having the encounter probability obtained in step S304 from the enemy character setting table in FIG. 6, and selects the enemy character shown in FIG. 7B. Set in the table. When various information of the selected enemy character is set in the enemy character selection table, the CP
U101 returns the process to step S304, and repeats the processes of steps S304 to S309 described above.

As described above, even if the own character has not moved to the hiding position, or even if the own character has moved to the hiding position, the values generated by all the random numbers are determined in accordance with the encounter probability. When the value is larger than the reference value, FIG.
Of the enemy character selection table of FIG.
On the other hand, when at least one of the values generated by the random numbers is equal to or smaller than the reference value, various information of the enemy character is set in the enemy character selection table of FIG. 7B. As a result,
When various information of the enemy character is set in the enemy character selection table of FIG. 7B, the enemy character is encountered.

Hereinafter, the battle process in step S110 of FIG. 8 will be described with reference to the flowchart shown in FIG.

In the battle process, first, the CPU 101
Displays a battle screen as shown in FIG. 15 on the television receiver 2 and prompts the user to input a battle operation (step S40).
1). That is, the CPU 101 displays an action selection dialog 62 including a plurality of fighting actions as selection items and a vertically movable cursor 63 on the battle screen between the player character 31 and the enemy character 61.

When a battle action in the action selection dialog 62 is selected by a player's operation, the CPU 101
Acquires the battle action at which the selection cursor 63 is located (step S402). The CPU 101 attacks the enemy character according to the acquired battle operation (step S403). That is, the CPU 101 displays the acquired battle operation of the own character, and subtracts a value corresponding to the predetermined damage from the HP of the enemy character shown in FIG. 7B.

When an enemy character is attacked, the CPU 101
Generates an attack action of the enemy character (step S4).
04). The CPU 101 attacks the own character in accordance with the generated battle action (step S405). That is, the CPU 101 displays the generated battle action of the enemy character, and displays the value corresponding to the predetermined damage in FIG.
It is subtracted from the HP of the own character shown in (c). CPU
101 determines whether or not the HP of the own character is 0 (step S406).

When it is determined that the HP of the own character is 0 (step S406; Yes), the CPU 101
The battle process ends, and the process returns to step S112 shown in FIG. On the other hand, when it is determined that the HP of the own character is not 0 (Step S406; No), it is determined whether the HP of all enemy characters in FIG. 7B is 0 (Step S407).

If it is determined that the HP of any one of the enemy characters is not 0 (step S407; No), the CPU 1
In step 01, the process returns to step S402, and the processes in steps S402 to S407 described above are repeated.

On the other hand, if it is determined that the HPs of all the enemy characters are 0 (step S407; Yes), the CP
U101 calculates the experience value and the amount of money (step S101).
408). That is, the CPU 101 obtains the total value of the acquired experience values and the acquired amounts of all the enemy characters in FIG. 7B and adds them to the accumulated experience value and the accumulated amount of FIG. 7C.

As described above, in the battle process, the player can freely select the enemy character selection table shown in FIG. 7B set by the encounter determination process shown in FIG. 13 and the own character state table shown in FIG. 7C. The enemy character encountered and the own character can be made to fight according to the encounter probability set in.

As described above, in this embodiment, the probability of encountering each enemy character is freely set by the player, and each enemy character can be encountered according to the set encounter probability. As a result, the player who has a desire to encounter the enemy character can frequently encounter the desired enemy character by setting the probability of encountering the enemy character to be encountered high.
The self-character can be efficiently grown. In addition, a player who does not want to encounter an enemy character can reduce the chance of encountering the enemy character by setting the probability of encountering the entire enemy character low, and can proceed with the development of the story. it can. Therefore, the player can comfortably proceed with the game without feeling wasted time and annoyance.

In the above embodiment, the encounter with the enemy character is determined based on whether or not the reference value set according to the encounter probability with each enemy character is equal to or less than a value generated by random numbers. The method of determining the encounter with the enemy character according to the above is arbitrary. For example, the CPU 10
1 sets the number of enemy characters according to the encounter probability in an arbitrary area of a predetermined table, and when the area selected at random from the table is the area where the enemy character is set, the enemy character is set. It may be determined that they have been encountered.

In the above embodiment, the encounter with the enemy character is determined according to the encounter probability of the enemy character set in advance so as to correspond to each of the predetermined areas. However, it is set so as to correspond to all the areas. According to the probability of encountering the enemy character including the common enemy character
The encounter with the enemy character may be determined. Further, the number of enemy characters encountered at one time is also arbitrary. For example, C
After selecting an arbitrary enemy character, the PU 101 generates one numerical value within a predetermined range, and increases or decreases the selected enemy character so as to be equal to the generated numerical value. That is, when there are more enemy characters selected than the generated numerical value, the CPU 101 excludes enemy characters in excess of the numerical value from the selection. Add enemy characters from already selected characters. As a result, it is possible to enrich the variations of the enemy characters encountered according to the encounter probability.

In the above-described embodiment, the case has been described where the present invention is implemented using the home game machine 1 as a platform. However, the present invention may be implemented with a personal computer, an arcade game machine, or the like.

In the above embodiment, the program for realizing the present invention is distributed using the CD-ROM 3 as a medium. However, the program for implementing the present invention may be stored in another computer-readable information recording medium such as a magnetic disk or a ROM card and distributed. Further, it may be preinstalled and distributed to the magnetic disk device of the system to which the present invention is applied. Alternatively, a program for implementing the present invention may be stored in a large-capacity storage medium provided in a Web server and distributed via the Internet.
