<Processing of Game Content Management Units 234a and 234b of Server Devices 2a and 2b>
In the game system 1 configured as described above, for example, if the service of the first game has to be terminated for some reason, the user cannot use the game content obtained in the first game. You may feel frustrated.

Therefore, in the game system 1 of the present embodiment, the service of one game is terminated based on a predetermined contract between the provider of the first game and the provider of the second game. At that time, the game media acquired by the user in one game can be used in the other game for a limited period of time.

Processing performed in the game system 1, in particular, processing performed by the game content management means 234a and 234b of the server devices 2a and 2b will be specifically described below. Since the processes executed by the game content management units 234a and 234b are basically the same, the following explanation will be made by exemplifying the case where the service of the first game ends.

When the game content management means 234b of the second server device 2b receives the service end notification transmitted from the service management means 233a of the first server device 2a with the end of the service of the first game, first, the game content management means 234b of the first game game content can be used in the second game. Specifically, as shown in FIG. 5, for example, the notification time of service termination notified from the service management means 233a of the first server device 2a is set to "t1", and the service termination time of the first game is set to "t2". Then, the game content management means 234b sets the notification time t1 as the start time ts, and sets a time later than the service end time t2 as the end time te. Then, the game content management means 234b sets the period from the start time ts to the end time te as a period during which the game content of the first game can be used in the second game. This period is hereinafter referred to as "available period T". In this embodiment, this usable period T corresponds to the predetermined period.

On the other hand, if the game content of the first game is to be used in the second game, the second server device 2b needs to obtain information on the characteristics of the game content. Therefore, when the service of the first game ends, the game content management means 234a of the first server device 2a transmits the game content characteristic information of the first game stored in the game content DB 222a to the second server device 2b. do. Upon receiving the game content characteristic information of the first game transmitted from the first server device 2a, the game content management means 234b of the second server device 2b stores it in the game content DB 222b.

Further, the game content management means 234b of the second server device 2b permits the use of the game content of the first game in the second game at the start time ts of the available period T. Specifically, the game content management means 234b not only uses the tokens to which the identification information of the second game is assigned among the tokens registered in the distributed ledger 321 of the blockchain system 4, but also the tokens of the first game. The use of the token to which the identification information is assigned is permitted in the second game.

As described above, the game content of the first game can be used in the second game with the same characteristics. In this embodiment, the game content that has the characteristics of the first game and can be used in the second game corresponds to the "first game content".
The game content management means 234b of the second server device 2b prohibits the use of the game content of the first game in the second game when the end time te of the usable period T has come. Specifically, the game content management means 234b allows only the tokens to which the identification information of the second game is assigned among the tokens registered in the distributed ledger 321 of the blockchain system 4 to be used in the second game. Permission is granted, and use of tokens to which the identification information of the first game is assigned is prohibited in the second game. As a result, the game content of the first game can be used in the second game only during the available period T.

In addition, in the game system 1 of the present embodiment, the first game, the second game, and the distributed ledger 321 of the blockchain system 4 all use common (or mutually linked) user identification information. ing. Therefore, the user can use the game content of the first game in the second game during the usable period T by simply logging into the second game using the account information of the first game.

The game content management means 234b of the second server device 2b determines whether the game content of the first game is used in the second game or used for transactions such as exchange or sale between users during the available period T. , the usage history and transaction history are registered in the distributed ledger 321 of the blockchain system 4 .

<Flow of Operation of Game System 1>
Next, with reference to FIG. 6, the flow of processing executed by the respective control units 23a and 23b of the server devices 2a and 2b when the service of the first game ends will be described.

As shown in FIG. 6, when it is determined that the service of the first game will end, the service management means 233a of the first server device 2a transmits a service end notification to the second server device 2b (step S10). The service end notification includes information such as the fact that the service of the first game will end, the notification time t1 of the service end, and the service end time t2. Also, the game content management means 234a of the first server device 2a transmits the game content characteristic information of the first game to the second server device 2b (step S11).

The game content management means 234b of the second server device 2b receives the service end notification transmitted from the first server device 2a (step S20), and also receives the game content characteristic information of the first game (step S21). The game content management means 234b determines the usable period T as shown in FIG. 5 based on the service end notification time t1 and service end time t2 included in the service end notification (step S22). The game content management unit 234b also causes the game content DB 222b to store the game content characteristic information transmitted from the first server device 2a (step S23).

Subsequently, the game content management means 234b determines whether or not the start time ts of the available period T has come (step S24), and if the start time ts has come (step S24: YES), Use of the game content of the first game in the game is permitted (step S25). Thereafter, the game content management means 234b determines whether or not the end time te of the available period T has come (step S26), and if the end time te has come (step S26: YES), the second game (step S27).

In summary, the control unit 33 (computer) of the game device 5 is divided into first game execution means (562) for executing the first game and second game execution means for executing the second game different from the first game. Means (563) and game medium providing means (564) for providing the first game medium to the user in the first game. Also, the control unit 23a (computer) of the first server device 2a is caused to function as game content providing means (235a) for providing the first game content to the user in the first game. Further, the controller 23b (computer) of the second server device 2b is caused to function as game content management means (234b) that makes the first game content available in the second game for a predetermined period.

<effect>
According to the game system 1 as described above, the user can use the game content of the first game in the second game during the usable period T. As a result, it is possible to prevent the game content given to the user in the first game from disappearing as it is, so that the user's dissatisfaction can be reduced.

As shown in FIG. 5, the game content management means 234b sets the usable period T from time ts during the service provision period of the first game to time te later than the service end time t2 of the first game. Set as a period. According to this configuration, the user can use the game content of the first game in the second game even after the service of the first game ends, so that the user's dissatisfaction can be further resolved. In addition, by limiting the period during which the game content can be used in the second game, it is possible to suppress the influence of changes in the game balance of the second game due to the game content brought from the first game. can.

<First modification>
Next, the 1st modification of the game system 1 of the said embodiment is demonstrated.
In the above embodiment, the configuration in which the game content of the first game is used as it is in the second game has been described as an example, but in such a configuration, the gameplay of the second game may be impaired.

For example, assume that the game content of the first game is a recovery item and the recovery amount is set to "1000". When the player character's maximum hit points in the first game is "5000", the effect of the recovery item is to restore the player character's hit points by 1/5, which is not a very large recovery effect. However, if the maximum hit points of the player character in the second game is "1000", the recovery item having the recovery effect of "1000" will have the maximum recovery effect. Therefore, if the recovery item of the first game is used as it is in the second game, the gameplay of the second game is greatly impaired.

Therefore, the game content management means 234b of the second server device 2b of this modification adjusts the characteristics of the game content when making the game content of the first game available. For example, the game content management means 234b sets the recovery effect to 1/5, ie, "200", in the case of the above recovery item.

The adjustment of the characteristics of the game content of the first game as described above is performed by, for example, the provider of the second game, and the content of the adjustment is stored in the game content DB 222b of the second server device 2b. The game content management means 234b of the second server device 2b determines the characteristics when the game content of the second game is used in the first game based on the adjustment details stored in the game content DB 222a.

Alternatively, the adjustment of the characteristics of the game content of the first game may be performed by the game content management means 234b of the second server device 2b. Specifically, the game content management unit 234b compares the game content property information of the second game stored in the game content DB 222b with the game content property information of the first game transmitted from the first server device 2a. By doing so, the adjustment amount when using the game content of the first game in the second game is calculated by an arithmetic expression or the like, and the calculated adjustment amount is stored in the game content DB 222b for each game content. Then, when the game contents of the first game are actually used in the second game, the game contents management means 234b controls the game contents based on the game contents characteristic information and the adjustment amount of the first game stored in the game contents DB 222b. Determining the properties of the game media for the first game.

When the game content management means 234b of the second server device 2b adjusts the characteristics of the game content of the first game, the game system 1 operates as shown in FIG. 7, for example.
As shown in FIG. 7, the game content management unit 234b of the second server device 2b determines whether or not it is necessary to adjust the characteristics of the game content of the first game (step S23). S30). For example, the game content management means 234b extracts the game content of the second game similar to the game content of the first game, and if there is a large difference in their effect values, the game content of the first game It is determined that it is necessary to adjust the characteristics of the medium (step S30: YES). In this case, the game content management unit 234b adjusts the characteristics of the game content of the first game by calculating the adjustment amount as described above (step S31).

After executing the process of step S31, the game content management means 234b of the second server device 2b executes the process of step S24 and after. Further, even if the game content management unit 234b makes a negative determination in the processing of step S30 (step S30: NO), that is, even if adjustment of the characteristics of the game content is not necessary, the processing after step S24 is performed. to run.

Note that the processes of steps S30 and S31 are individually performed for a plurality of game contents of the first game that can be used in the second game. That is, the adjustment of characteristics is individually performed for a plurality of game contents of the first game.
In the game system 1 of this modified example, the game content whose characteristics are not adjusted is used in the second game while maintaining the characteristics of the first game. In this modification, the game content used in the second game while maintaining the characteristics of the first game corresponds to the "first game content". In addition, the game media used in the second game after the characteristics of the first game are adjusted correspond to the "second game media" corresponding to the first game media. In the following description, the terms first game content and second game content are used with such definitions.

According to the configuration of the game system 1 of the present modification as described above, it is possible to avoid spoiling the gameplay of the second game when making the game content of the first game available in the second game.
<Second modification>
Next, a second modification of the game system 1 of the above embodiment will be described.

When the game content of the first game is used in the second game, it is assumed that the game content corresponding to the game content of the first game does not exist in the second game. For example, in the first game, an attack means that consumes magic points exists as an attack means, but if there is no attack means that consumes magic points in the second game, the item for recovering magic points is the first game. It will be present in the game but not in the second game. In such a case, the game content of the first game cannot be used as it is in the second game.

Therefore, in the process of step S31 shown in FIG. 7, the game content management unit 234a of the second server device 2b of the present modification, if the game content corresponding to the game content of the first game does not exist in the second game, The properties of the game media for the first game are changed to properties that can be used in the second game. For example, if there is an attack means that consumes stamina in the second game, the game content management means 234a changes the effect of the item for recovering magic points to the effect for recovering stamina. In this modified example, the game media whose characteristics have been changed correspond to the second game media.

Such actual adjustment of the characteristics of the game content of the first game is performed, for example, by the provider of the second game, and the content of the adjustment is stored in the game content DB 222b of the second server device 2b. The game content management means 234b determines the characteristics when using the game content of the first game in the second game based on the adjustment details stored in the game content DB 222b.

According to the configuration of the game system 1 of the present modification as described above, even if the game content of the first game does not exist in the second game, the game content corresponding to the game content of the first game is transferred to the second game. Since it can be used in a game, it is possible to further resolve the user's dissatisfaction.

<Third modification>
Next, the 3rd modification of the game system 1 of the said embodiment is demonstrated.
When the game media of the first game are made available in the second game as the first game media or the second game media, the utility value of the game media may change. For example, if the popularity of the second game is higher than the popularity of the first game, the game content of the first game is used in the second game rather than the utility value of using the game content of the first game in the first game. The utility value in the case of doing so is higher. In such a case, for example, if the game contents of the first game can be used in the second game as they are, the user of the second game will not only feel dissatisfied, but at worst, the gameplay of the second game may be greatly impaired. There is

Therefore, the game content management unit 234b of the present embodiment is configured to calculate the difference between the utility value of the game medium in the first game and the utility value when the game medium is used as the first game medium or the second game medium in the second game. The usable period T is changed based on the utility value fluctuation amount.
For example, the game content management means 234b determines the utility value of the game content based on the degree of popularity of each of the first game and the second game. Specifically, the game content management unit 234b quantifies the popularity of each of the first game and the second game based on the number of players of each of the first game and the second game. Then, the game content management means 234b uses a value obtained by subtracting the popularity of the first game from the popularity of the second game as the utility value fluctuation amount, and can use the utility value fluctuation amount by using an arithmetic expression or a map. Calculate the period T. The calculation formula and the map are set such that, for example, the larger the utility value fluctuation amount, that is, the higher the degree of popularity of the second game relative to the first game, the shorter the available period T.

The game content management means 234b may determine the utility value fluctuation amount using only the popularity of the first game or only the popularity of the second game. That is, the game content management means 234b may determine the utility value fluctuation amount based on the degree of popularity of at least one of the first game and the second game.

On the other hand, in the above embodiment, the game content of the first game is available only in the game provided by the second server device 2b. It may be possible to use not only the game provided, but also the game provided by another server device. That is, the game content of the first game may be usable in multiple second games. In such a case, the game content management unit 234b can use the number of second games in which the game content of the first game can be used as the utility value fluctuation amount. Note that the number of second games in which the game content of the first game can be used is counted in advance by, for example, an operator or the like and stored in the storage unit 22a of the second server device 2b. The game content management means 234b calculates the usable period T from the utility value fluctuation amount using an arithmetic expression and a map. The calculation formula and the map are set such that, for example, the larger the utility value fluctuation amount, that is, the larger the number of second games in which the game content of the first game can be used, the shorter the available period T is.

Also, although there are multiple second games that can use the game content of the first game, the user may be playing only a few of the multiple second games. In such a case, the game content management means 234b may determine the utility value fluctuation amount based on the number of second games actually played by the user among the plurality of second games. Note that information on the number of second games actually played by the user may be stored in the user DB 221a of each of the plurality of server devices 2b if, for example, user account information is shared among a plurality of second games. can be obtained by counting the number of user identities stored in the .

Information on the number of second games actually played by the user may be stored in the distributed ledger 321 as tokens. In this case, a part of each play log of the user may be stored in the token, or information indicating that the play log has satisfied a predetermined condition may be stored in the token. Accordingly, information on the number of second games whose play logs satisfy the predetermined condition can be specified based on the information stored in the token. If the play log is the user's playing time of a specific second game or game progress information, the predetermined condition is that the playing time of the specific second game is longer than a predetermined time and the game has progressed to a specific scene. , can be adopted. Also, the play log that satisfies a predetermined condition may be consent to the terms of use of a specific second game. Also in this case, it may be specified that the user has at least played the second game. By specifying the number of specific second games that satisfy a predetermined condition in this way, it is possible to specify information about the number of second games actually played by the user.

As described above, the game content management means 234b of this modification can be used based on the amount of change in utility value, which is the deviation between the utility value of the game medium in the first game and the utility value of the game medium in the second game. Set a period T. As a result, it is possible to set the usable period T more appropriately, so that it is possible to further eliminate the user's dissatisfaction.

<Fourth modification>
Next, a fourth modification of the game system 1 of the above embodiment will be described.
The game content management unit 234b of the second server device 2b of the present modified example uses the utility value fluctuation amount described in the third modified example to obtain the game content of the first game in the process of step S31 shown in FIG. Adjust the characteristics when used in the second game as the first game medium or the second game medium.

Specifically, the game content management unit 234b uses the utility value fluctuation amount as the degree of popularity of the first game, the number of second games in which the game content of the first game can be used, Use the number of second games actually played. The storage unit 22b of the second server device 2b stores in advance a map that can determine the effect and effective period of the game media from the fluctuation amount of the utility value such as the popularity of the first game as shown in FIG. It is

In the map shown in FIG. 8, the type of game content of the first game, the degree of popularity of the first game, the total number of second games in which the game content of the first game can be used, and the user's actual are associated with the number of actual plays of the second game currently being played, and the effect and validity period when the game content of the first game is used as the first game content or the second game content. In this map, each parameter such as the degree of popularity of the first game is stratified into "A" indicating the highest level, "B" indicating the intermediate level, and "C" indicating the lowest level. For example, if the game media are recovery items I1 to I4, the recovery item I1 whose effect is set to "A" has the effect of fully recovering both the player character's HP (hit points) and MP (magic points). . The recovery items I3 and I4 whose effect is set to "B" have the effect of fully recovering the player character's HP and recovering only half of the MP. The recovery item I2 whose effect is set to "C" has the effect of fully recovering only the player character's HP.

In this modification, the effect and validity period when using the game content of the first game as the first game content or the second game content shown in FIG. Corresponds to the characteristic.
The map shown in FIG. 8 may be created by the provider of the second game, or may be created by the game content management means 234b of the second server device 2b. The game content management means 234b uses the map shown in FIG. 8 to determine the characteristics when using the game content of the first game as the first game content or the second game content.

As described above, the game content management means 234b of the present modification calculates the second 2 Set the characteristics of the game media in the game. As a result, it is possible to more appropriately set the characteristics of the game content when using the game content of the first game in the second game, so that it is possible to further resolve the dissatisfaction of the user.

<Fifth Modification>
Next, a fifth modification of the game system 1 of the above embodiment will be described.
The display control means 567 of the game device 5 of this modified example executes the processing shown in FIG. As shown in FIG. 9, the display control means 567 first determines whether or not the available period T is reached (step S40). When the display control unit 567 determines that the usable period T is reached (step S40: YES), the user can display the game media usable in the second game through the game action of the first game, gacha, or the like. It is determined whether or not it is newly acquired (step S41). When the display control means 567 determines that a new game content usable in the second game has been acquired (step S41: YES), the display control means 567 displays a notification screen 70 as shown in FIG. 10 on the display 61 ( step S42).

As shown in FIG. 10, the notification screen 70 displays a sentence that, for example, when the user newly acquires item A as a game medium, that item A can be used in another game. . Note that the notification screen 70 illustrates a case where there are two games, “game B” and “game C”, as the second games in which the newly acquired item A can be used.

Shift buttons 71 and 72 are provided on the notification screen 70 . The transition buttons 71 and 72 are buttons for playing game B and game C, respectively. That is, the user can switch from the first game to game B or game C by operating the switch button 71 or 72 .

As described above, the display control means 567 of the present modified example, when the user newly acquires a game content that can be used in the second game in the first game during the available period T, displays the first game content as shown in FIG. A notification screen 70 prompting the user to shift from the first game to the second game is displayed. This makes it easier to prompt the user from the first game to the second game.

<Sixth modification>
Next, a sixth modification of the game system 1 of the above embodiment will be described.
The display control means 567 of the game device 5 of this modified example executes the processing shown in FIG. As shown in FIG. 11, the display control means 567 first determines whether or not the available period T is reached (step S50). When the display control unit 567 determines that the usable period T is reached (step S50: YES), the display control unit 567 selects the game contents of the first game given to the user that can be used in the second game. It is determined whether or not game media exist (step S51). In addition, in this modification, it is assumed that only part of the game contents of the first game can be used in the second game.

When the display control means 567 determines that there are game contents that can be used in the second game (step S51: YES), the game contents list screen showing a list of target game contents is displayed on the display 61. display (step S52). This game content list screen is provided with transition buttons 71 and 72 for prompting transition from the first game to game B or game C as shown in FIG.

As described above, the display control means 567 of the present modified example, when the user possesses the game content that can be used in the second game in the available period T in the first game, changes from the first game to the second game. Display a screen prompting the user to migrate. This makes it easier to prompt the user from the first game to the second game.

<Seventh Modification>
Next, a seventh modification of the game system 1 of the above embodiment will be described.
As indicated by the dashed line in FIG. 4, the control unit 56 of the game device 5 of this modified example further functions as selection means 568 . The selection means 568 performs the processing shown in FIG. The selection means 568 determines whether or not the available period T has passed (step S60). When the selection means 568 determines that the usable period T has passed (step S60: YES), the selection means 568 causes the display 61 to display a screen for allowing the user to select one of the plurality of second games. The controller 567 is instructed (step S61).

Subsequently, the selection means 568 determines whether or not any one of the plurality of second games has been selected (step S62), and if it is determined that it has been selected (step S62: YES), the selection The second game information received is transmitted to the first server device 2a (step S63).

When the game content management means 234a of the first server device 2a receives the second game selection information transmitted from the first server device 2a (step S70), all the game content owned by the user in the first game Alternatively, part of it is forcibly converted into game media that can be used in the second game (step S71). This conversion of the game content is accompanied by the adjustment of the characteristics, etc., as described in the first modification and the second modification, for example.

According to such a configuration, it becomes easier for the user to shift from the first game to the second game.
