It is permitted and the use of the token to which the identification information of the first game is given is prohibited in the second game. As a result, the game medium of the first game can be used in the second game only during the available period T.

In the game system 1 of the present embodiment, user identification information common to all of the first game, the second game, and the distributed ledger 321 of the blockchain system 4 (or linked to each other) is used. ing. Therefore, if the available period is T, the user can use the game medium of the first game in the second game only by logging in to the second game using the account information of the first game.

The game medium management means 234b of the second server device 2b is used when the game medium of the first game is used in the second game or is used for a transaction such as exchange or sale between users during the available period T. Registers the usage history and transaction history 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 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 is terminated, the service management means 233a of the first server apparatus 2a transmits a service termination notification to the second server apparatus 2b (step S10). The service end notification includes information such as the fact that the service of the first game is terminated, the service end notification time t1, and the service end time t2. Further, the game medium management means 234a of the first server device 2a transmits the game medium characteristic information of the first game to the second server device 2b (step S11).

The game medium 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 medium characteristic information of the first game (step S21). The game medium management means 234b determines the available period T as shown in FIG. 5 based on the service end notification time t1 and the service end time t2 included in the service end notification (step S22). Further, the game media management means 234b stores the game media characteristic information transmitted from the first server device 2a in the game media DB 222b (step S23).

Subsequently, the game medium management means 234b determines whether or not the start time ts of the usable period T has been reached (step S24), and if the start time ts has come (step S24: YES), the second. The use of the game medium of the first game in the game is permitted (step S25). After that, the game medium management means 234b determines whether or not the end time te of the usable period T has been reached (step S26), and if the end time te has come (step S26: YES), the second game. The use of the game medium of the first game in the above is prohibited (step S27).

Summarizing the above, the control unit 33 (computer) of the game device 5 executes the first game execution means (562) for executing the first game and the second game execution for executing the second game different from the first game. It functions as a means (563) and a game medium giving means (564) for giving a user a first game medium in the first game. Further, the control unit 23a (computer) of the first server device 2a is made to function as a game medium giving means (235a) for giving the user the first game medium in the first game. Further, the control unit 23b (computer) of the second server device 2b is made to function as a game medium management means (234b) that makes the first game medium available for a predetermined period in the second game.

<Effect>
According to the game system 1 as described above, the user can use the game medium of the first game in the second game during the available period T. As a result, it is possible to prevent the game medium 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 medium management means 234b sets the available period T from the time point ts during the service provision period of the first game to the time point te later than the service end time point t2 of the first game. Set as a period. According to this configuration, even after the service of the first game is terminated, the user can use the game medium of the first game in the second game, so that the user's dissatisfaction can be further resolved. Further, by limiting the period during which the game medium can be used in the second game, it is possible to suppress the influence of the game medium being brought from the first game on the change in the game balance of the second game. can.

<First modification>
Next, a first modification of the game system 1 of the above embodiment will be described.
In the above embodiment, the configuration in which the game medium 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 game characteristics of the second game may be impaired.

For example, it is assumed that the game medium of the first game is a recovery item, and the recovery amount is set to "1000". When the maximum hit point of the player character in the first game is "5000", the effect of the recovery item is an effect of recovering the hit point of the player character by 1/5, which is not a very large recovery effect. However, when the maximum hit point of the player character of the second game is "1000", the recovery item having the recovery effect of "1000" has the maximum recovery effect. Therefore, if the recovery item of the first game is used as it is in the second game, the game quality of the second game is greatly impaired.

Therefore, the game medium management means 234b of the second server device 2b of the present modification adjusts the characteristics of the game medium when the game medium of the first game is made available. For example, in the case of the above recovery item, the game medium management means 234b sets the recovery effect to "200", which is 1/5.

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

Alternatively, the characteristics of the game medium of the first game may be adjusted by the game medium management means 234b of the second server device 2b. Specifically, the game medium management means 234b compares the game medium characteristic information of the second game stored in the game medium DB 222b with the game medium characteristic information of the first game transmitted from the first server device 2a. By doing so, the adjustment amount when the game medium of the first game is used in the second game is calculated by an calculation formula or the like, and the calculated adjustment amount is stored in the game medium DB 222b for each game medium. Then, when the game medium of the first game is actually used in the second game, the game medium management means 234b is based on the game medium characteristic information of the first game and the adjustment amount stored in the game medium DB 222b. Determine the characteristics of the game medium of the first game.

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

The game medium management means 234b of the second server device 2b executes the processing of step S31 and then the processing of step S24 and subsequent steps. Further, even when the game medium management means 234b makes a negative judgment in the process of step S30 (step S30: NO), that is, even when it is not necessary to adjust the characteristics of the game medium, the process after step S24. To execute.

The processes of steps S30 and S31 are individually performed on a plurality of game media of the first game that can be used in the second game. That is, the adjustment of the characteristics is performed individually for the plurality of game media of the first game.
In the game system 1 of this modification, the game medium whose characteristics are not adjusted will be used in the second game while maintaining the characteristics in the first game. In this modification, the game medium used in the second game while maintaining the characteristics in the first game corresponds to the "first game medium". Further, the game medium used in the second game whose characteristics in the first game are adjusted corresponds to the "second game medium" corresponding to the first game medium. In the following, the terms of the first game medium and the second game medium are used in such a definition.

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

When the game medium of the first game is used in the second game, it is assumed that the game medium corresponding to the game medium of the first game does not exist in the second game. For example, in the first game, there is an attack means that consumes magic points as an attack means, but in the second game, if there is no attack means that consumes magic points, the item that recovers the magic points is the first item. It exists in the game but does not exist in the second game. In such a case, the game medium 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 medium management means 234a of the second server device 2b of the present modification is when the game medium corresponding to the game medium of the first game does not exist in the second game. The characteristics of the game medium of the first game are changed to the characteristics 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 medium management means 234a changes the effect of the item that recovers the magic points to the effect that recovers stamina. In this modification, the game medium after the characteristics are changed corresponds to the second game medium.

Such actual adjustment of the characteristics of the game medium of the first game is performed by, for example, a business operator who provides the second game, and the adjustment content is stored in the game medium DB 222b of the second server device 2b. The game medium management means 234b determines the characteristics when the game medium of the first game is used in the second game based on the adjustment content stored in the game medium DB 222b.

According to the configuration of the game system 1 of the present modification as described above, even if the game medium of the first game does not exist in the second game, the game medium corresponding to the game medium of the first game is used as the second game medium. Since it can be used in games, it is possible to further eliminate user dissatisfaction.

<Third modification example>
Next, a third modification of the game system 1 of the above embodiment will be described.
When the game medium of the first game is made available in the second game as the first game medium or the second game medium, the utility value of the game medium may fluctuate. For example, if the popularity of the second game is higher than the popularity of the first game, the game medium is used in the second game rather than the utility value when the game medium of the first game is used in the first game. The utility value is higher when doing so. In such a case, for example, if the game medium of the first game can be used as it is in the second game, not only the user of the second game feels dissatisfied, but if it worsens, the game quality of the second game may be significantly impaired. There is.

Therefore, the game medium management means 234b of the present embodiment has a deviation 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 amount of fluctuation in the utility value.
For example, the game medium management means 234b determines the utility value of the game medium based on the popularity of each of the first game and the second game. Specifically, the game medium management means 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 medium 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 be used from this utility value fluctuation amount by using an arithmetic expression or a map. Calculate the period T. In the calculation formula or the map, for example, the larger the fluctuation amount of the utility value, that is, the higher the popularity of the second game with respect to the first game, the shorter the usable period T is set.

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

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

Further, although there are a plurality of second games that can use the game medium of the first game, there is a possibility that only a small number of games among the plurality of second games are played by the user. In such a case, the game medium management means 234b may determine the amount of fluctuation in the utility value based on the number of the second games actually played by the user among the plurality of second games. The information on the number of second games actually played by the user is, for example, when the user's account information is shared by a plurality of second games, the user DB 221a of each of the plurality of server devices 2b is used. It can be obtained by counting the number of user identification information stored in.

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 satisfies a predetermined condition may be stored in the token. Thereby, the information on the number of the second games in which the play log satisfies the predetermined condition can be specified based on the information stored in the token. When the play log is the play time of a specific second game or the progress information of the game of the user, the game is advanced to the play time of the specific second game and the specific scene for a predetermined time or longer as a predetermined condition. , Can be adopted. Further, the play log satisfying a predetermined condition may be a consent to the terms of use of a specific second game. Again, it can be determined that the user has at least played the second game. In this way, by specifying the number of specific second games that satisfy the predetermined conditions, it is possible to specify information on the number of second games that the user is actually playing.

As described above, the game medium management means 234b of this modification can be used based on the amount of fluctuation in the 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 the period T. As a result, the usable period T can be set more appropriately, and the user's dissatisfaction can be further resolved.

<Fourth modification>
Next, a fourth modification of the game system 1 of the above embodiment will be described.
The game medium management means 234b of the second server device 2b of the present modification uses the utility value fluctuation amount described in the third modification in the process of step S31 shown in FIG. 7, and uses the game medium of the first game. The characteristics when used in the second game as the first game medium or the second game medium are adjusted.

Specifically, the game medium management means 234b has the popularity of the first game, the number of second games that can use the game medium of the first game, and the user among a plurality of second games as the amount of fluctuation in the utility value. Use the number of second games you are actually playing. In the storage unit 22b of the second server device 2b, a map capable of determining the effect and validity period of the game medium from the amount of fluctuation in the utility value such as the popularity of the first game as shown in FIG. 8 is stored in advance. Has been done.

In the map shown in FIG. 8, the type of the game medium of the first game, the popularity of the first game, the total number of the second games that can use the game medium of the first game, and the user actually among the plurality of second games. The actual number of plays of the second game being played, and the effect and validity period when the game medium of the first game is used as the first game medium or the second game medium are associated with each other. In this map, each parameter such as the 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, when the game medium is recovery items I1 to I4, the recovery item I1 whose effect is set to "A" has the effect of fully recovering both the HP (hit points) and MP (magic points) of the player character. .. The recovery items I3 and I4 whose effect is set to "B" have the effect of fully recovering the HP of the player character 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 HP of the player character.

In this modification, the effect and validity period when the game medium of the first game shown in FIG. 8 is used as the first game medium or the second game medium is the same as when the game medium of the first game is used in the second game. Corresponds to the characteristic.
The map shown in FIG. 8 may be created by a business operator providing the second game, or may be created by the game medium management means 234b of the second server device 2b. The game medium management means 234b determines the characteristics when the game medium of the first game is used as the first game medium or the second game medium by using the map shown in FIG.

As described above, the game medium management means 234b of this modification is based on the amount of fluctuation in the 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. 2 Set the characteristics of the game medium in the game. As a result, the characteristics of the game medium when the game medium of the first game is used in the second game can be set more appropriately, so that the user's dissatisfaction can be further resolved.
