  In this embodiment, except for the case where the game is executed from the beginning, the game data read from the memory card 5 at the start of the game is read into the related data storage area 12b and read in this way. The game is resumed according to the game data.

  Further, the authentication server (management server) group 111 according to the present embodiment shown in FIG. 3 manages the above-described user authentication, manages the user entry / exit, and notifies the status change to other server groups at the time of status change. Etc. Here, a configuration example of user account information prepared for a game player that can be registered in the profile server 115 will be described.

  The user account is composed of, for example, one master account and three sub-accounts, and the configuration of each account is the same. Each account is composed of a content account composed of user identification information and a profile account. The profile account is a 64-byte active handle that identifies the currently selected handle ID, a server connection status flag indicating whether the user is online (running a network game) or offline, the user Whether the game execution status of the game is, for example, “hidden” state, “seating” information indicating leaving from the game machine, “normal”, “automatic response”, “BUSY (busy)”, etc. Online status information is provided.

  Further, the profile account includes handle specifying information for specifying, for example, 64 areas of handle names (names used by the player for the player character in the game during the game execution) when the player executes the game. Yes.

  Next, game execution control in the present embodiment having the above-described configuration will be described with reference to flowcharts and the like. The following processing is performed by the game apparatus body 2 executing a game program stored in the CD-ROM / DVD-ROM 4. In the case of a network game, these processes are implemented by controlling the sharing of game data with other game execution players via the server group 102.

  FIG. 6 is a flowchart showing a processing procedure of weather setting in the game field, which is characteristic of the game, in the game control in the game system according to the present embodiment. First, in step S1 in the figure, the following basic processing is executed. That is, when the player sets the CD-ROM / DVD-ROM 4 on which the execution game program is recorded in the game apparatus body 2, the necessary program is read from the CD-ROM / DVD-ROM 4 and stored in the RAM 12. Is done. Then, an initial screen (for example, a logo of a game development manufacturer) is displayed, the memory card 5 is checked, a game title is displayed on the screen, and data is loaded.

  When the above processing is completed, a game selection screen for selecting which game data to select from the game save data related to the game read from the memory card 5 is displayed, and game data to be executed is selected. Next, the game data is read from the selected game data file, stored in the related data storage area 4b of the RAM 12, and the game is started from the save point. If there is no saved data, that is, if a game is to be completely started, there is no game file, so a new game is started.

  If the game is a network game, the user logs in to the authentication server (management server) group 111 to request authentication, and requests game participation. The authentication server (management server) group 111 that has received the authentication notifies other servers such as the profile server 115 of the game participation of the player. The player can now access the profile server 115.

  In step S2 of FIG. 6, the basic setting about the weather in a game field is performed. That is, in the game system according to the present embodiment, control is performed so that the weather in the field changes according to a predetermined schedule for a predetermined period (for example, one year). Therefore, in this step S2, a setting for changing the weather for each field of the game and a setting for causing a monster to appear according to the weather as described later are performed.

  Specifically, the main control unit 11 schedules the transition of weather for each field in the basic setting in step S2 and executes a process of tabulating the appearance rate of monsters due to weather. To do. Here, four types of “sunny” “cloudy” “mist” “rain” can be set as basic weather.

  In step S <b> 3, the main control unit 11 refers to the schedule for the weather in the field set in advance in the above step (confirmation of the weather schedule). In the subsequent step S4, the field is specified, and the scheduled weather is searched for the specified field. These processes determine, for example, the weather in the identified field over a period of one year.

  In step S5, the main control unit 11 sets the weather in the field according to the above determination. The set weather is displayed on the display screen 61 together with the actual field screen in the subsequent step S6.

  In step S <b> 7, the main control unit 11 outputs the sound effect (for example, rain sound if “rain”) set and displayed in the above step from the speaker 62. Thereafter, the main control unit 11 returns the process to step S3 again, and checks whether or not the weather schedule has changed. If there is no change in the weather schedule, the already determined weather is continuously set in the field, but if the weather schedule changes, the field weather is changed according to the changed schedule (step S4).

  FIG. 7 is a flowchart showing a control procedure of an enemy character (monster appearing in the field) appearing in the game in relation to the weather of the field. The main control unit 11 confirms the current weather in the identified field in step S11 of FIG. 7, and resets a predetermined timer in step S12 if the weather can be confirmed. Then, in step S13, the main control unit 11 refers to the monster appearance rate table shown in FIG.

  In other words, the monster appearance rate table in FIG. 8 is a table showing the appearance probability (percentage) of monsters corresponding to the weather at that time. For example, if the weather is “sunny”, it means that birdman is most likely to appear and no sahagin appears. However, when it is raining, Sahagin appears with a 100% probability, and Birdman is the least likely to appear. Here, a monster appearance rate table is provided for each field of the game.

  In step S14, it is determined whether or not the player is in battle with the monster in the weather set and displayed as described above. In this battle, the player is forced to change the way of fighting with the monster due to the weather, thereby improving the game's preference.

  In the game control according to the present embodiment, not only the change in the appearance rate of monsters according to the weather described above but also the time control described below is performed. That is, after the battle ends (NO in step S14), in step S15, for example, it is determined whether or not a predetermined time has elapsed since the battle ended based on the result of the timer measurement. This is a determination routine for making the appearance rate of an appearing monster after it falls once in battle until it reappears change with time.

  In other words, when a monster loses and disappears, it is necessary to elapse a predetermined time controlled and managed by the timer before the monster reappears. And if predetermined time passes, a process will be returned to step S11 again and the present weather confirmation will be started.

  Note that the number of monsters appearing in one field as a result of the determination in step S13 is not limited to only one monster having the highest appearance rate, but the appearance rate shown in the table of FIG. In response, multiple monsters appear.

  Next, the searching ability of the monster appearing in the game will be described. Here, a case will be described in which an appearing monster has abilities such as vision, smell, hearing, and magic perception. FIG. 9 is a flowchart showing a search control procedure for a monster having the above-mentioned ability. Here, since the visual priority is higher than the olfactory sense, when searching for a battle, the enemy with the visual priority is executed.

  Therefore, as shown in step S21 of FIG. 9, it is first determined whether or not the sight of the monster is valid. If the vision is valid, in step S22, processing for visually tracking the player character operated by the player (visual tracking processing) is executed. However, if the vision is not effective, the effectiveness of the olfaction is determined in step S23. If the ability is effective, an olfactory tracking process is performed in step S24.

  If none of the abilities are valid, the monster determines whether or not hearing is valid in step S25. If the auditory sense is valid, the player character is tracked by the auditory sense (auditory tracking process) in subsequent step S26. If hearing is not effective, it is determined in step S27 whether magic perception is effective. Magic perception is the ability to search for an enemy that senses that other characters are using magic, regardless of the normal five senses. If the monster has magic perception, a tracking process (magic perception tracking process) using the ability is executed in step S28.

  As a result of the respective tracking processes, in step S31, the monster can catch up with the player character, and the battle between the player character operated by the player and the monster is started.

  Note that the priority order of the visual, olfactory, auditory, and magic perception abilities is not limited to the above-described example. For example, for a certain monster, the olfactory search enemy is given priority over the visual sense. May be set to give priority to all abilities. By doing this, it is possible to give the enemy search characteristics according to the monster.

  By the way, from the viewpoint that the ability of the monster has the above-mentioned ability depends on the situation (environmental condition) at that time, it is set so that the priority order of the above-mentioned sensing ability is determined by the environmental condition, especially the weather mentioned above. Also good. In other words, the setting is such that the monster's searching ability is affected by the weather. Specifically, when the weather is “rainy”, the monster's vision is reduced, and the visual range of the enemy is reduced to half of the normal range. In comparison, a wider range of capabilities may be preferentially used.

  Also, in the case of “rain” (or a severe noise situation), the sound of the rain (or noise) causes a decrease in hearing, and the search range by hearing is narrowed. May be. Furthermore, you may enable it to set these fall of a sensing capability for every opponent (player character) to fight. That is, when a certain monster fights against a specific opponent, the setting is such that hearing is always reduced.

  Furthermore, in the above embodiment, the appearance rate of monsters varies depending on the weather. However, the daily time zone may be taken into consideration for this weather setting. For example, in the field, a tendency is set such that it is sunny in the morning and rainy after the evening (including the night), thereby further changing the battle situation. By doing this, the taste is added to the game.

  As described above, according to the present embodiment, an enemy character corresponding to the weather in the field appears in the field, and the search enemy having the widest search range among a plurality of abilities (search capability) of the enemy character. Use the ability preferentially to make the enemy character perform the search action. Then, after the enemy character catches up with the player character by the search enemy action, the enemy character and the player character start a battle.

  In other words, since the search range of the enemy character changes its search range according to the weather in the field, the priority order of the capability is changed, and among the changed abilities, the one with the wide search range is preferentially used. At the same time, the enemy character continues to exhibit the searching ability until the battle with the player character is started, so that the player of the game changes according to the enemy character appearing in the field according to the weather and the weather of the field. It is necessary to take into consideration the enemy character's searching ability. Therefore, the battle situation after the enemy character catches up with the player character due to the search-behind behavior is changed, and it is possible to further improve the taste of the game.

  Also, by managing the field weather data in a table, it is possible to increase game variations with a smaller amount of data.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the invention. For example, the appearance probability of a monster may be managed not only by corresponding to the weather at that time but also by dividing a plurality of monsters into groups. Specifically, monster A and monster B are registered as belonging to the same group. For example, if the random number appearance probability is less than 50%, monster A appears, and the probability is 50% or more. If there is, it may be set so that monster B appears and either monster A or B appears.

  In the above description, the case where the present invention is realized using a home-use game machine as a platform has been described. However, the present invention may be realized using a general-purpose computer such as a personal computer or an arcade game machine as a platform.

  Further, in the above-described embodiment and its modifications, programs and data for realizing the present invention are stored in a CD-ROM / DVD-ROM, and this CD-ROM / DVD-ROM is used as an information recording medium. Yes. However, the information recording medium is not limited to a CD-ROM / DVD-ROM, and may be another magnetic or optical recording medium that can be read by a computer, such as a magnetic disk or a ROM card, or a semiconductor memory. Good.

  Further, the program and data for realizing the present invention are not limited to a form provided by a medium such as a CD-ROM / DVD-ROM that can be attached to and detached from a game machine or a computer, but to realize the present invention. The data may be received from another device connected via a communication line or the like, for example, a server group and recorded in a memory. Furthermore, the program or data may be recorded in a memory on another device connected via a communication line or the like, and the program or data may be used via the communication line or the like.
