<About scenario change processing>
Hereinafter, scenario change processing performed by the scenario change means 565 will be described in detail with reference to FIG.

  FIG. 2 is a diagram conceptually showing how the game scenario cn according to the present embodiment changes (specifically, the transition of the story from the past to the future).

  The scenario cn includes a plurality of stories sr0 to sr5. The ongoing story is changed at branch points p1 to p5 that branch from one story to another story. In the present embodiment, these branch points p1 to p5 do not automatically appear in a valid state when the story approaches the branch point, but appear in a valid state by using the predetermined game medium described above. To do.

  In this embodiment, the case where the predetermined game media are branch flags A to E is illustrated. When the set game media are the branch flags A to E (predetermined game media), the scenario changing unit 565 causes the branch points p1 to p5 corresponding to the branch flags A to E to appear in a valid state. Then, the scenario changing unit 565 changes the scenario of the game to be progressed from the branch points p1 to p5 that appear in an effective state.

  Specifically, when none of the branch flags A to E are set, the game proceeds according to the story sr0 based on the user's operation (normal route). At this time, a default game screen corresponding to the story sr0 is displayed on the display 61. If the game progresses with the normal route, the normal end is developed as the ending of the game.

  It is assumed that the setting unit 564 incorporates the branch flag A as a predetermined game medium on the game program in accordance with the user operation while the story sr0 is in progress. Then, as shown in FIG. 2, a branch point p1 corresponding to the branch flag A appears. The scenario changing means 565 changes the ongoing scenario sr0 to a different story sr1 at the branching point p1, thereby changing the scenario being progressed by the game progressing means 562.

  Further, when the user sequentially selects the predetermined game media “branch flags B to E”, the setting unit 564 sequentially incorporates the branch flags B to E into the game program according to the user's operation. Then, a branch point p2 corresponding to the branch flag B, a branch point p3 corresponding to the branch flag C, a branch point p4 corresponding to the branch flag D, and a branch point p5 corresponding to the branch flag E appear one after another. The scenario changing means 565 changes the ongoing scenario 562 by changing the ongoing stories sr1 to sr4 to different stories sr2 to sr5 at the appearing branch points p2 to p5. Let

  When the game progresses with the roots of the stories sr1 to sr5 after the change, the content corresponding to the stories sr1 to sr5 is developed in the ending of the game.

For example, when the content of the game is a character breeding simulation mainly in a high school, the following (a) to (f) are developed as the endings of the stories sr0 to sr5.
(A) Story sr0: Normal ending "Leave a mediocre life without club activities"
(B) Story sr1: Bad ending 1 “Graduates without being able to participate in the game once in club activities”
(C) Story sr2: Bad ending 2 “I graduate after losing my first match at Inter High”
(D) Story sr3: Bad ending 3 “Failure with repeated defeats and failure”
(E) Story sr4: Happy ending 4 “Inspires after a dramatic reunion with a surviving brother”
(F) Story sr5: Miracle End “Winning at Inter High”
As described above, the endings of the stories sr1 to sr5 changed according to the set branch flags A to E are ranked up or down from the endings of the stories sr0 to srr before the change.

  In the present embodiment, for convenience of explanation, “A to E” is added to the names of the branch flags corresponding to the branch points p1 to p5, but the branch flags A to E are all of the same type. This is because, if the types of the branch flags A to E are different from each other, even if the branch flag B has already been acquired from the server device 2, the branch flag B cannot be effectively used unless the branch flag A is acquired yet. It is. On the other hand, in this embodiment, since all the branch flags A to E are of the same type, the branch points p1 to p5 appear according to the number of branch flags that have been set.

  That is, when the lottery selection unit 233 of the server device 2 selects the same type of predetermined game media by lottery and the setting unit 564 of the game device 5 sets these, the scenario changing unit 565 is set. The degree of change of the scenario is varied according to the number of predetermined game media.

<A flow of a series of processes in the game system 1>
The flow of a series of processes in the game system 1 including the game media lottery process and the scenario change process will be described with reference to FIGS.

  As a premise, it is assumed that the game progress means 562 of the game apparatus 5 is progressing according to the downloaded game program.

  For example, it is assumed that the screen sc1 of FIG. 4A is displayed on the display 61 of the game apparatus 5, and the user presses the “pull gacha” button bt1 from the screen sc1. Then, the lottery request unit 563 generates a game media download request, and the communication unit 561 transmits the download request to the server device 2 via the network interface 51 (# 11).

  When the information processing unit 231 of the server device 2 receives the download request (# 12), the lottery selection unit 233 selects an arbitrary game medium by lottery (# 13). The distribution means 234 transmits the selected game medium to the game apparatus 5 via the network interface 21 (# 14).

  When the communication means 561 of the game apparatus 5 receives the game medium (# 15), the screen sc2 of FIG. 4B is displayed on the display 61. When the “OK” button bt2 on the screen sc2 is pressed by the user, the received game content is stored in the storage unit 55 (# 16).

  For example, a screen sc3 of FIG. 5 is displayed on the display 61 in response to a user operation. This screen sc3 exemplifies a case where a story route relating to a scenario and an unused game medium currently stored in the storage unit 55 are displayed in a selectable list. When a predetermined game medium as a branch flag is selected from the screen sc3 and the setting button bt3 is pressed, the setting unit 564 performs a process for setting the predetermined game medium (# 17).

  Note that the game medium (including the branch flag) once used for setting is deleted from the storage unit 55 and is not displayed in the list on the screen sc3.

  The communication unit 561 transmits a download request to the server device 2 for the game program of another story that can be branched at the branch points p1 to p5 that have appeared in the setting process (# 18).

  When the information processing unit 231 of the server device 2 receives the download request (# 19), the distribution unit 234 extracts the corresponding game program from the storage unit 22 and transmits it (# 20).

  When the communication unit 561 of the game apparatus 5 receives the game program (# 21), the scenario change unit 565 updates the game program that the game progress unit 562 is in progress (# 22). Thereby, the game scenario changes according to the set predetermined game medium (branch flag).

  In the scenario change, with the change of the story, a new event occurs for the character in the game, a recollection scene is added, etc., the description deepens, the character's voice, tone, etc. Or change.

  Until the game progresses and the ending corresponding to the currently ongoing story is reached (NO in # 23), game device 5 and server device 2 repeat the above-described series of operations. When the ending of the story in progress is reached (Yes in # 23), the game progress means 562 displays the ending game screen corresponding to the story on the display 61 (# 24).

  In summary, the game program of the present embodiment causes the control unit 56 (computer) of the game apparatus 5 to function as the game progress means 562 for progressing the game, and the control unit 23 (computer) of the server apparatus 2 is used as the user. Based on the above operation, the game device 5 is caused to function as lottery selection means 233 for selecting an arbitrary game medium from among a plurality of game media related to the game by lottery, and the control unit 56 (computer) of the game apparatus 5 is selected as the selected game medium. In the case of a predetermined game medium (specifically, a branch flag), the game progressing means 562 functions based on the predetermined game medium as a scenario changing means 565 that changes the scenario of the game being advanced. .

<Effect of the invention>
According to the game program of the present embodiment, a predetermined game medium (specifically, a branch flag) that affects the game scenario is selected by lottery based on the user's operation, and is in progress based on the predetermined game medium. The game scenario changes. Therefore, the user can feel as if they are intervening in the appearance of a branch point where the scenario changes, and a more interesting game is executed.

  When the same type of branch flag is selected as a predetermined game medium a plurality of times by lottery, the scenario changing unit 565 changes the degree of change of the scenario according to the number. Therefore, the scenario of the game is more varied and the interest is improved.

[Second Embodiment]
In the present embodiment, a case will be described in which the predetermined game medium is not a “branch flag” but a “keyword”. Other than this difference, for example, the configuration of the game system 1 is the same as that of the above embodiment.

<About scenario change processing>
FIG. 6 conceptually shows how the scenario cn of the game according to the present embodiment changes (specifically, the transition of the story from the past to the future) in the same way as in FIG. .

  In the present embodiment, the game media lottery selected by the lottery selection means 233 includes keywords that are predetermined game media in addition to characters, items, and voices of characters. The keyword is one of a plurality of constituent elements that constitute an appearance condition for causing the branch points p1 and p2 from one story to another story to appear. Therefore, the branch points p1 and p2 appear according to the combination of keywords.

  Specifically, the scenario cn includes a plurality of stories sr0 to sr2. The branch point p1 that branches the story sr0 to another story sr1 appears in an effective state when one keyword “alien” and one keyword “UFO” are set by the setting means 564. The branch point p2 for branching the story sr0 to another story sr2 is in an effective state when one keyword “win”, two keywords “loving”, and one keyword “courage” are set by the setting means 564. Appear.

  The scenario changing unit 565 changes the scenario by changing the progressing story from the story sr0 to the story sr1 or the story sr2 at each of the appearing branch points p1 and p2. As a result, if the game progresses in the story sr0, the normal end ending is displayed on the display 61. If the story sr1, the other end is displayed on the display 61. If the story sr2 is displayed, the good end ending is displayed on the display 61. The

<A flow of a series of processes in the game system 1>

  When the lottery request unit 563 generates a game medium download request in response to the user's operation in FIG. 4A, the communication unit 561 transmits this to the server apparatus 2 via the network interface 51 (# 31). .

  When the information processing unit 231 of the server device 2 receives the download request (# 32), the lottery selection unit 233 selects an arbitrary game medium by lottery (# 33). The distribution means 234 transmits the selected game medium to the game apparatus 5 via the network interface 21 (# 34).

  When the communication means 561 of the game apparatus 5 receives the game medium (# 35), the game medium is stored in the storage unit 55 (# 36). Note that the game media stored in the storage unit 55 are displayed as a list on the display 61 so as to be selectable as in FIG.

  When a predetermined game medium as a keyword is selected from a list-displayed screen by a user operation, the setting means 564 performs a setting process for the predetermined game medium (# 37). Note that the game media (including keywords) once used for setting are deleted from the storage unit 55 and are not displayed in a list.

  When the appearance conditions of the branch points p1 and p2 are satisfied by a combination of a plurality of keywords (that is, predetermined game media) (Yes in # 38), the communication unit 561 can branch at the appearing branch points p1 and p2. For the game program of another story, a download request is transmitted to the server device 2 (# 39).

  If the appearance conditions of the branch points p1 and p2 are not satisfied (No in # 38), the game device 5 and the server device 2 repeat the above-described operation without proceeding to the subsequent processing.

  When the information processing unit 231 of the server device 2 receives the download request (# 40), the distribution unit 234 extracts the corresponding game program from the storage unit 22 and transmits it (# 41).

  When the communication unit 561 of the game apparatus 5 receives the game program (# 42), the scenario change unit 565 updates the game program that the game progression unit 562 is in progress (# 43). Thereby, the scenario of a game changes because the story changes from the appearing branch points p1 and p2.

  Even in the scenario change, as in the first embodiment, as the story changes, a new event occurs for a character in the game, a recollection scene is added, etc. The voice or tone of the character changes.

  Until the game story reaches the ending (NO in # 44), the game device 5 and the server device 2 repeat the series of operations described above. When the story reaches the ending (# 44: Yes), the game progress means 562 displays the ending corresponding to the progressed story on the display 61 (# 45).

  In summary, the game program of the present embodiment causes the control unit 56 (computer) of the game apparatus 5 to function as the game progress means 562 for progressing the game, and the control unit 23 (computer) of the server apparatus 2 is used as the user. Based on the above operation, the game device 5 is caused to function as lottery selection means 233 for selecting an arbitrary game medium from among a plurality of game media related to the game by lottery, and the control unit 56 (computer) of the game apparatus 5 is selected as the selected game medium. In the case of a predetermined game medium (specifically, a keyword) that has been set to affect the game scenario, a scenario for changing the game scenario that the game progression means 562 is making progress based on the predetermined game medium It functions as the changing means 565.

<Effect of the invention>
According to the game program of the present embodiment, a predetermined game medium (specifically, a keyword) that affects a game scenario is selected by lottery based on a user's operation, and an ongoing process is performed based on the predetermined game medium. The game scenario changes. In particular, in the present embodiment, the predetermined game medium is one of a plurality of constituent elements that constitute an appearance condition for causing a branch point from one story to another story to appear. A branch point appears in an effective state depending on a combination of keywords, and the scenario changes from the branch point. Therefore, the user can feel as if he / she is intervening in the appearance of a branch point where the scenario changes, in particular, making the branch point into an effective state, and an entertaining game is executed.

  In the second embodiment, as in the first embodiment, the scenario changing unit 565 may vary the degree of scenario change according to the number of keywords set. For example, when there are three set keywords, a recollection scene is added, and when four keywords are set, a recollection scene different from the recollection scene can be added.

  In the first embodiment, the process of changing the degree of change of the scenario according to the number of set keywords is not always essential.

  Moreover, in the said 1st Embodiment, when the process which changes the change degree of a scenario is performed, the kind of branch flag AE may not be the same but may differ. In this case, in FIG. 2, for example, the branch flag B can be utilized after the branch flag A is acquired.

  In the first and second embodiments, when a plurality of predetermined game media of the same type (branch flag or keyword) are stored in the storage unit 55 to the extent that they are no longer necessary for a scenario change, the predetermined game media May be converted into elements that can be used for other purposes in the game.

  In the first and second embodiments, a plurality of characters may appear in the game scenario. In this case, there is a scenario for each character, and the scenario for each character can be changed. In addition, a change in the scenario of one character may have some influence on the scenario of another character.

  In the first and second embodiments, when the game scenario changes, for example, the story does not change, and only the game image including an object (such as a character's clothes) included in the story may change.

  In the first and second embodiments, the lottery selection means 233 of the server device 2 may select only predetermined game media that are set to affect the game scenario by lottery. In this case, the scenario changing unit 565 of the game apparatus 5 immediately sets the scenario without performing a determination process as to whether or not the predetermined game medium set by the setting unit 564 has been set to affect the game scenario. Processing to be changed can be performed.

  A plurality of game apparatuses 5 may be provided. Also, a plurality of server devices 2 may be provided.

  In the first and second embodiments, the setting unit 564 performs a predetermined game medium setting process according to the user's operation, so that the branch point appears in a valid state, and the story route corresponding to the branch point is automatically generated. The case of being selected is illustrated. However, the game program may be one in which the user can freely select a desired branch point or story root from among a plurality of branch points that have appeared in the setting process so far. In this case, the scenario changing means 565 can change the story of the scenario to the story root when the branch point or the story root is selected.

  In the first and second embodiments, when a predetermined game medium is selected from a list-displayed screen (for example, the screen sc3 in FIG. 5), the setting process of the predetermined game medium is performed. Illustrated. However, when the setting unit 564 of the game apparatus 5 receives the predetermined game medium from the server apparatus 2, the setting means 564 may immediately perform the setting process of the predetermined game medium without the selection operation by the user.

  In the first and second embodiments, the game apparatus 5 determines whether or not to set a predetermined game medium in order to make the branch point effective when the ongoing story approaches the branch point. A screen for asking questions may be displayed on the display 61.

  In the above, when a story in progress approaches a branch point, there is a case where a predetermined game medium for making the branch point effective is not stored in the storage unit 55. In that case, the game apparatus 5 may display on the display 61 a screen for prompting acquisition of the predetermined game medium (for example, a screen sc1 for drawing a gacha in FIG. 4A).

  In the first and second embodiments, the game media that has been set once may not necessarily be deleted from the storage unit 55.

  In the first and second embodiments, the predetermined game medium used for the scenario change may be obtained by combining or strengthening game media selected by the server device 2 by lottery. In other words, a new branch point may appear when the predetermined game medium obtained by synthesis or enhancement is set by the setting means 564.

  In the first and second embodiments, the length of the story in the scenario may change instead of the appearance of a branch point according to the predetermined game medium that has been set. For example, according to a predetermined game medium for which setting processing has been performed, the story can be continued until a normal ending, or can be continued until a later date (after story) after the ending.

  In the above, the length of the story may be different depending on the rarity of the predetermined game medium on which the setting process has been performed. For example, when a predetermined game medium having a normal level of rarity is set, the story continues until the ending. When a predetermined game medium having a high level of rarity has been set, the end point of the story can be continued until a later story (after story) after the ending.

  Even when these other embodiments are employed, the effects of the present invention are exhibited. In addition, this embodiment, other embodiments, and other embodiments can be appropriately combined.
