[0061] [Functional configuration of the control unit in the server device] 1, the control unit 13 of the server device 10 has a first game executing unit 101, a second game executing unit 102, and a management unit 103. Specifically, the control unit 13 functions as the first game executing unit 101, the second game executing unit 102, and the management unit 103 by the CPU executing various programs.

[0062] <First Game Execution Division> The first game executing unit 101 executes the first game. Specifically, the first game executing unit 101 generates and transmits game data for executing the first game based on the first game data 41 stored in the storage unit 12.

[0063] <2nd Game Execution Department> The second game executing unit 102 executes the second game. Specifically, the second game executing unit 102 generates and transmits game data for executing the second game based on the second game data 42 stored in the storage unit 12.

[0064] <Management Department> The management unit 103 manages users and games. The management unit 103 manages various data stored in the storage unit 12. The management unit 103 performs processing related to the blockchain (for example, generating transactions, etc.).

[0065] In this example, the management unit 103 converts a first game medium owned by the user into a second game medium owned by the user.

[0066] In addition, the management unit 103 registers, in a blockchain (distributed network / distributed ledger), historical data indicating that a first game medium owned by the user has been converted into a second game medium owned by the user.

[0067] Furthermore, the management unit 103 grants the second game medium to the user depending on the results of the user's play of the first game.

[0068] [Data stored in the memory unit of the game device] 2, the storage unit 25 of the game device 20 stores block chain data 50. The block chain data 50 stored in the storage unit 25 is the same as the block chain data 50 stored in the storage unit 12 of the server device 10.

[0069] [Functional configuration of the control unit in the game device] As shown in Fig. 2, the control unit 26 of the game device 20 has a game progression unit 201 and a blockchain management unit 202. Specifically, the control unit 26 functions as the game progression unit 201 and the blockchain management unit 202 by the CPU executing various programs.

[0070] <Game Progression Division> The game progression unit 201 executes a game in response to control by the first game executing unit 101 (or the second game executing unit 102) of the server device 10. Specifically, the game progression unit 201 receives game data, controls the display 31 and speaker 32 based on the game data, and transmits operation information indicating operations input to the game device 20 (specifically, the game controller 33).

[0071] In this example, the game progression unit 201 controls the graphics processing unit 22 and the audio processing unit 23, and thereby controls the display 31 and the speaker 32. The game progression unit 201 also receives operation information transmitted from the operation unit 24, and transmits this operation information to the server device 10.

[0072] In addition, the game progression unit 201 responds to control by the management unit 103 of the server device 10, and causes various operation screens to be displayed on the display 31.

[0073] <Blockchain Management Department> The blockchain management unit 202 manages the blockchain data 50. The blockchain management unit 202 performs processing related to the blockchain (for example, updating the blockchain data, etc.).

[0074] [Registration process] Next, the registration process performed in the game system 1 of the first embodiment will be described. The registration process is a process for registering the game medium granted to the user in the first game (or the second game). In the following description, a case where the first game medium granted to the user in the first game is registered will be taken as an example. When the first game medium is granted to the user in the first game, the management unit 103 performs the following process.

[0075] First, the management unit 103 registers the first game medium provided to the user in the first game medium DB 51 corresponding to that user.

[0076] Furthermore, the management unit 103 generates a transaction including history data indicating which user was granted what amount of the first game medium. Specifically, the management unit 103 detects a blockchain ID assigned to the user to whom the first game medium was granted from the user DB 40. The management unit 103 then generates history data indicating the detected blockchain ID, the first game medium granted to the user, and the amount of the first game medium, and generates a transaction including the history data.

[0077] Next, the management unit 103 registers the newly generated transaction in a blockchain (distributed network / distributed ledger). Specifically, in the blockchain, a process (blockchain processing) is performed for the newly generated transaction to add a new block including the transaction to the blockchain data 50. Well-known blockchain technology can be adopted for this blockchain processing.

[0078] In this way, by performing blockchain processing, the blockchain data 50 stored in each of the multiple nodes that make up the blockchain is updated to new blockchain data 50 with new blocks added.

[0079] [Conversion process] Next, the conversion process performed in the game system 1 of the first embodiment will be described with reference to Fig. 9 (flowchart) and Fig. 10 (conceptual diagram). The change process is a process for converting a first game medium owned by a user into a second game medium owned by the user. The conversion process is an example of a game control method.

[0080] When an operation for starting a change process (change operation) is input to the game controller 33 by a user playing the first game, the management unit 103 performs the following process in response to the change operation. For example, the change operation is an operation of pressing a button for starting the change process on the operation screen displayed on the display 31.

[0081] <Step S11> First, the management unit 103 selects first game media to be subject to the conversion process from among the first game media owned by the user in the first game.

[0082] Specifically, the management unit 103 controls the game progression unit 201 of the game device 20 to display on the display 31 a list screen (not shown) showing the first game media owned by the user in the first game. The list screen can be generated based on the first game medium DB 51. The user operates the game controller 33 to select the first game media that the user wishes to convert to second game media and the quantity of those first game media from the list screen displayed on the display 31. When the user selects the first game media and the quantity of those first game media, the management unit 103 subjects the quantity of first game media selected by the user to the conversion process.

[0083] <Step S12> Next, the management unit 103 converts the first game medium selected in step S11 into a second game medium, and grants the second game medium to the user.

[0084] Specifically, the management unit 103 detects second game media corresponding to the first game media selected in step S11 from the conversion table 60. Then, the management unit 103 grants the detected second game media to the user in the quantity selected in step S11. In addition, the management unit 103 deletes the first game media selected in step S11 from the first game media owned by the user in the first game in the quantity selected in step S11.

[0085] <Step S13> The management unit 103 registers the second game medium provided to the user in step S12 in the second game medium DB 52 corresponding to that user.

[0086] Furthermore, the management unit 103 generates a transaction including history data indicating which user's amount of first game media was converted into which amount of second game media. Specifically, the management unit 103 detects a blockchain ID assigned to the user who instructed the conversion process from within the user DB 40. The management unit 103 then generates history data indicating the detected blockchain ID, the first game media deleted by the conversion process and their quantity, and the second game media added by the conversion process and their quantity, and generates a transaction including the history data.

[0087] Next, the management unit 103 registers the newly generated transaction in a blockchain (distributed network / distributed ledger). Specifically, in the blockchain, a blockchain process (a process for adding a new block including the transaction to the blockchain data 50) is performed on the newly generated transaction.

[0088] In this way, by performing blockchain processing, the blockchain data 50 stored in each of the multiple nodes that make up the blockchain is updated to new blockchain data 50 with new blocks added.

[0089] [Granting process] Next, the granting process performed in the game system 1 of the first embodiment will be described with reference to Fig. 11. When the user is playing the first game, the management unit 103 repeatedly performs the following process.

[0090] <Step S21> The management unit 103 determines whether or not the play result in the first game corresponds to a predetermined play result that has been set in advance. Specifically, the management unit 103 determines whether or not the play result in the first game corresponds to any of the play results (play results in the first game) registered in the grant table 70. If the play result in the first game corresponds to the predetermined play result, the process of step S22 is performed.

[0091] <Step S22> The management unit 103 grants the second game media to the user according to the play result of the first game. Specifically, the management unit 103 detects the second game media and the quantity thereof corresponding to the play result of the first game from the granting table 70. The management unit 103 then grants the detected quantity of the second game media to the user.

[0092] <Step S23> The management unit 103 registers the second game medium provided to the user in step S22 in the second game medium DB 52 corresponding to that user.

[0093] Furthermore, the management unit 103 generates a transaction including history data indicating which user was granted what amount of second game media. Specifically, the management unit 103 detects a blockchain ID assigned to the user to whom the second game media was granted from the user DB 40. The management unit 103 then generates history data indicating the detected blockchain ID, the second game media granted to the user, and the amount of the second game media, and generates a transaction including the history data.

[0094] Next, the management unit 103 registers the newly generated transaction in a blockchain (distributed network / distributed ledger). Specifically, in the blockchain, a blockchain process (a process for adding a new block including the transaction to the blockchain data 50) is performed on the newly generated transaction.

[0095] In this way, by performing blockchain processing, the blockchain data 50 stored in each of the multiple nodes that make up the blockchain is updated to new blockchain data 50 with new blocks added.

[0096] [Summary of embodiment 1] To summarize the above, the game system 1 of embodiment 1 comprises a first game execution unit 101 that executes a first game, which is a game that progresses in a first virtual space in response to user operation and in which a first game medium is owned by the user, a second game execution unit 102 that executes a second game, which is a game that progresses in a second virtual space different from the first virtual space in response to user operation and in which a second game medium different from the first game medium is owned by the user, and a management unit 103 that converts the first game medium owned by the user into a second game medium owned by the user.

[0097] [Advantages of the First Embodiment] As described above, in the game system 1 of the first embodiment, the first game medium owned by the user in the first game is converted into the second game medium owned by the user in the second game, thereby making it possible to transfer the game medium from the first game to the second game. This can increase the user's motivation to play games more than if the user were simply made to play the first game.

[0098] In addition, in the first embodiment, historical data indicating that a first game medium owned by a user has been converted into a second game medium owned by the user is registered in a blockchain (distributed network / distributed ledger). This allows the transfer of game medium from the first game to the second game to be managed by the blockchain, thereby enhancing resistance to data tampering.

[0099] Furthermore, in the first embodiment, the second game medium is awarded to the user depending on the results of the user's play of the first game, which can increase the user's motivation to play games (particularly the first game).

[0100] (Embodiment 2) The game system 1 of the second embodiment differs from the game system 1 of the first embodiment in the conversion table 60 and the operation of the management unit 103. The other configurations of the game system 1 of the second embodiment are similar to those of the game system 1 of the first embodiment.

[0101] In the second embodiment, the value of the second game medium after the change by the management unit 103 (value in the second game) is lower than the value of the first game medium before the change by the management unit 103 (value in the first game).

[0102] The management unit 103 converts the first game medium into a second game medium having a value lower than that of the first game medium. Specifically, the management unit 103 converts the first game medium into a second game medium having a quantity lower than that of the first game medium. The management unit 103 also converts the first game medium into a second game medium having a level lower than that of the first game medium.

[0103] As shown in Fig. 13, in the conversion table 60 of the second embodiment, a "first game medium" is associated with a "second game medium having a lower value than the value of the first game medium." For example, the record in the first row of the conversion table 60 in Fig. 13 indicates that a quantity of "3" of a currency called "gold" in the first game corresponds to a quantity of "1" of "zeny" in the second game. The record in the second row of the conversion table 60 in Fig. 13 indicates that a quantity of "1" of a food item called "apple (large)" in the first game corresponds to a quantity of "1" of a recovery item called "recovery potion (small)" in the second game.

[0104] Furthermore, in the second embodiment, the value of the second game medium after conversion by the management unit 103 changes depending on the play time of the second game by the user. In this example, the value of the second game medium after conversion by the management unit 103 increases as the play time of the second game by the user increases.

[0105] The management unit 103 measures the play time of the second game by the user. Then, the management unit 103 converts the first game medium into the second game medium such that the value of the second game medium changes according to the play time of the second game by the user. In this example, the management unit 103 converts the first game medium into the second game medium such that the value of the second game medium increases as the play time of the second game by the user increases.

[0106] Specifically, in the second embodiment, the storage unit 12 of the server device 10 stores a plurality of conversion tables 60. Each of the plurality of conversion tables 60 corresponds to a different play time (a play time of the second game by the user). In this example, as the play time corresponding to a conversion table 60 becomes longer, the value of the second game medium associated with the first game medium in that conversion table 60 becomes higher.

[0107] For example, the play time corresponding to the conversion table 60 of FIG. 13 is longer than the play time corresponding to the conversion table 60 of FIG. 12. In the first row record of the conversion table 60 of FIG. 13, a quantity of "1" of "Zenny" is associated with a quantity of "3" of "Gold" which is less than the quantity of "5" in the first row record of the conversion table 60 of FIG. 12. In the second row record of the conversion table 60 of FIG. 13, a quantity of "1" of "medium recovery potion" which is a higher level than the quantity of "1" of "small recovery potion" in the second row record of the conversion table 60 of FIG. 12 is associated with a quantity of "1" of "large recovery potion".

[0108] Then, the management unit 103 selects a conversion table 60 from the multiple conversion tables 60 that corresponds to the measured play time (the play time of the second game by the user), and performs a conversion process (step S12) using the selected conversion table 60.

[0109] [Effects of the second embodiment] The game system 1 of the second embodiment can provide the same effects as those of the game system 1 of the first embodiment. For example, since the game medium can be transferred from the first game to the second game, the user's motivation to play games can be increased more than when the user is simply made to play the first game.

[0110] Furthermore, in the second embodiment, the value of the second game medium after conversion by the management unit 103 is lower than the value of the first game medium before conversion by the management unit 103. This makes it possible to prevent a second game medium with a higher value than the value of the first game medium before conversion from being given to a user, and to prevent a collapse in the value of the second game medium in the second game.

[0111] Furthermore, in the second embodiment, the value of the second game medium after conversion by the management unit 103 changes depending on the play time of the second game by the user. Specifically, the longer the play time of the second game by the user, the higher the value of the second game medium after conversion by the management unit 103. This can increase the user's motivation to play games (particularly the second game).

[0112] (Embodiment 3) The game system 1 of the third embodiment differs from the game system 1 of the first embodiment in the details of the first game and the operation of the management unit 103. The other configurations of the game system 1 of the third embodiment are similar to those of the game system 1 of the first embodiment.

[0113] In the third embodiment, the first game includes a third game. The third game is a game compatible with the second game. Specifically, a virtual area in which the third game can be executed is provided in a first virtual space, which is the game space of the first game. Then, the user can play the third game by moving a player character into that virtual area.

[0114] In the third game, the player character of the first game can perform actions similar to those of the player character in the second game, in addition to the actions in the first game. For example, in the above virtual area, the player character of the first game can defeat enemy characters, in addition to building a house using materials.

[0115] Furthermore, in the third embodiment, the management unit 103 grants the second game medium to the user depending on the play result of the third game by the user. Specifically, the storage unit 12 of the server device 10 stores the grant table 80 of Fig. 14 in addition to (or instead of) the grant table 70 of Fig. 8. The grant table 80 indicates the correspondence between the play result in the third game and the second game medium.

[0116] 14, the correspondence between play results in the third game and the second game media is registered in the grant table 80. Examples of play results in the third game for which the second game media is granted include achieving a predetermined condition in the third game, defeating a specific enemy character in the third game, etc.

[0117] [Granting process] Next, the granting process performed in the game system 1 of the third embodiment will be described with reference to Fig. 15. When the user is playing the third game, the management unit 103 repeatedly performs the following process.

[0118] <Step S31> The management unit 103 determines whether or not the play result in the third game corresponds to a predetermined play result that has been set in advance. Specifically, the management unit 103 determines whether or not the play result in the third game corresponds to any of the play results (play results in the third game) registered in the grant table 80. If the play result in the third game corresponds to the predetermined play result, the process of step S32 is performed.

[0119] <Step S32> The management unit 103 grants the second game media to the user according to the play result of the third game. Specifically, the management unit 103 detects the second game media and the quantity thereof corresponding to the play result of the third game from the granting table 80. The management unit 103 then grants the detected quantity of the second game media to the user.

[0120] <Step S33> The management unit 103 registers the second game medium provided to the user in step S32 in the second game medium DB 52 corresponding to that user.

[0121] The management unit 103 also generates a transaction including history data indicating which user was granted what amount of second game media. Note that the process performed in step S33 is similar to the process performed in step S23. Specifically, blockchain processing is performed on the newly generated transaction. Then, the blockchain data 50 stored in each of the multiple nodes constituting the blockchain is updated to new blockchain data 50 to which a new block has been added.

[0122] [Effects of the Third Embodiment] The game system 1 of the third embodiment can provide the same effects as those of the game system 1 of the first embodiment. For example, since the game medium can be transferred from the first game to the second game, the user's motivation to play games can be increased more than when the user is simply made to play the first game.

[0123] Furthermore, in the third embodiment, the second game medium is awarded to the user depending on the result of the user's play of the third game, which can increase the user's motivation to play games (particularly the third game).

[0124] (Embodiment 4) The game system 1 of the fourth embodiment differs from the game system 1 of the first embodiment in the operation of the management unit 103. Other configurations of the game system 1 of the fourth embodiment are similar to those of the game system 1 of the first embodiment.

[0125] In the fourth embodiment, the management unit 103 automatically converts the first game medium owned by the user into the second game medium when the user plays the second game.

[0126] [Conversion process] Next, the conversion process performed in the game system 1 of the fourth embodiment will be described with reference to Fig. 16 (flowchart). When the user starts playing the second game, the management section 103 performs the following process.

[0127] <Step S41> The management unit 103 detects from the blockchain data 50 a block that includes a blockchain ID assigned to the user and historical data related to the first game medium.

[0128] <Step S42> Next, the management unit 103 generates (updates) the first game media DB 51 based on the history data contained in the block detected in step S41.

[0129] <Step S43> Next, the management unit 103 converts the first game media registered in the first game media DB 51 generated (updated) in step S42 into second game media and grants the second game media to the user. Specifically, the management unit 103 converts all of the first game media registered in the first game media DB 51 that are convertible (i.e., the first game media registered in the conversion table 60) into second game media based on the conversion table 60.

[0130] <Step S44> The management unit 103 registers the second game medium provided to the user in step S43 in the second game medium DB 52 corresponding to that user.

[0131] [Effects of the fourth embodiment] The game system 1 of the fourth embodiment can provide the same effects as those of the game system 1 of the first embodiment. For example, since the game content can be transferred from the first game to the second game, the user's motivation to play games can be increased more than when the user is simply allowed to play the first game.

[0132] (Other embodiments) In the above description, a life simulation game is given as an example of the first game, and an action game is given as an example of the second game, but the present invention is not limited to these. For example, other examples of the first game and the second game include sports games such as baseball and soccer, fighting games, war games, management simulation games that allow players to experience managing a restaurant or the like that involves entertaining guests, and occupational simulation games that allow players to experience occupations such as idols, taxi drivers, train drivers, police officers, and farmers.

[0133] In addition, in the above description, a private blockchain has been given as an example of the blockchain, but the blockchain is not limited to this. For example, the blockchain may be a public blockchain or a consortium blockchain.

[0134] In the above description, the first game media DB 51 and the second game media DB 52 are stored in the storage unit 12 of the server device 10, but the present invention is not limited to this. For example, the first game media DB 51 and the second game media DB 52 may be generated from the blockchain data 50 as necessary.

[0135] In the above description, the first game executing unit 101, the second game executing unit 102, and the management unit 103 are provided in the control unit 13 of the server device 10, but the present invention is not limited to this. For example, the first game executing unit 101, the second game executing unit 102, and the management unit 103 may be provided in the control unit 26 of the game device 20. In this case, data such as the conversion table 60 may be stored in the storage unit 12 of the server device 10.

[0136] The conversion process by the management unit 103 can be executed even after the service (distribution) of the first game has ended. This allows the first game media of the first game whose service has ended to be converted into second game media of the second game for effective use.

[0137] In the above description, the second game medium obtained by the conversion process in the management unit 103 may be a game medium that cannot be acquired in the current second game. For example, the first game medium may be associated with a "second game medium that cannot be acquired in the current second game" in the conversion table 60. Examples of such game media include game media that can be acquired for a limited time, game media that can be acquired in an old version of the game but cannot be acquired in a new version of the game, etc.

[0138] In addition, in the above description, the management unit 103 may convert the second game medium owned by the user in the second game into the first game owned by the user in the first game. Note that conversion from the second game medium to the first game medium can be realized by a process similar to the conversion from the first game medium to the second game medium in the above description.

[0139] In the above description, the management unit 103 may grant the first game medium to the user depending on the play result of the second game. The granting of the first game medium depending on the play result of the second game can be realized by the same process as the granting of the second game medium depending on the play result of the first game in the above description.

[0140] Examples of play results in the second game for which the first game medium is provided include achieving a predetermined condition in the second game, presenting an item to another player character or a non-player character, etc. Examples of predetermined conditions include obtaining a predetermined item, creating a predetermined item, increasing the level of the player character, defeating a predetermined enemy character, etc.

[0141] In the above description, after the first game medium is converted into a second game medium (hereinafter referred to as "second game medium A") by the management unit 103, a new second game medium (hereinafter referred to as "second game medium B") may be generated in the second game using the second game medium A. Then, the second game medium B may be converted into a new first game medium by the management unit 103.

[0142] Furthermore, the second game medium A may be a game medium that cannot be obtained within the second game. The second game medium B may be a game medium that cannot be obtained within the second game and can only be created by a generation method that uses the second game medium A.

[0143] In the game system 1 of the second embodiment, an event similar to an event occurring in the first game may occur in the third game. For example, a building such as a house may be destroyed by an enemy character in a virtual area in which the third game is played. Also, in the third game, it may be possible to insure a building such as a house. By insuring a building in this way, when the building is destroyed by an attack by an enemy character, the repair cost of the building can be reduced (or reduced to zero).

[0144] In addition, in the game system 1 of embodiment 2, the player character of the second game may be able to move from the second virtual space, which is the game space of the second game, to a virtual area of ​​the first virtual space (a virtual area in which the third game can be played) in response to user operation.

[0145] When a player character of the second game moves from the second virtual space to the virtual area of ​​the first virtual space, the character model of the player character of the second game may be converted to the character model of the first game. Similar to the conversion of the game medium, the management unit 103 may convert the character model of the player character moving from the second virtual space to the virtual area of ​​the first virtual space based on a character conversion table indicating the correspondence between the character models of the first game and the character models of the second game.

[0146] The converted character model of the player character moving from the second virtual space to the virtual area of ​​the first virtual space may be a character model that cannot be used in the normal first game. For example, if the character model in the first game is an "animal" and the character model in the second game is a "hunter," the character model that cannot be used in the normal first game may be an "animal in a hunter guise."

[0147] In the above description, currency and items are given as examples of the first game medium, but the first game medium is not limited to these. Other examples of the first game medium include a character model of the player character, a companion character who is a companion of the player character, and the like. The same applies to the second game medium. For example, the character model of the player character, companion character, and the like may be registered in the conversion table 60 indicating the correspondence between the first game medium and the second game medium.

[0148] In the above description, the first game medium (or the second game medium) may be traded between the user and a non-player character appearing in the first game (or the second game). Furthermore, history data indicating the content of the trade of the game medium between the user and the non-player character may be registered in the blockchain.

[0149] Specifically, the management unit 103 may generate historical data indicating a blockchain ID assigned to the user who sold (or purchased) the game medium, an ID assigned to the non-player character who purchased (or sold) the game medium, and the details of the purchase and sale of the game medium, and generate a transaction including the generated historical data.

[0150] Even when these other embodiments are adopted, the effects of the present invention are exhibited. In addition, this embodiment can be combined with other embodiments, and other embodiments can be combined with each other as appropriate. The above embodiments are essentially preferred examples, and are not intended to limit the scope of the present invention, its applications, or its uses. [Industrial Applicability]
