Server device, non-transitory server device-readable storage medium, and game system

A non-transitory server device-readable storage medium storing a program executed by a server device that is connected to a first player terminal used by a first player and a second player terminal used by a second player so as to communicate with each other,

• the program causing the server device to execute the following processes:
• a process to store in a storage unit player information in which each of items owned by players are associated with each of the players;
• a reception process
• to receive, from the first player terminal, an exchange request to exchange a first item owned by the first player for a second item different from the first item,
• and receive, from the second player terminal after the exchange request, an acquisition request that the second player acquire the first item in an exchange source from the first player;
• a judgment process to judge whether or not the second player owns the second item based on the player information when the acquisition request is received in the reception process;
• and
• an item exchange process
• when it is judged that the second player owns the second item in the judgment process, to set the second item owned by the second player as a candidate item to be exchanged for the first item in the exchange source,
• and when it is judged that the second player does not own the second item in the judgment process, to transmit a game image for purchase to the second player terminal, the game image being for allowing the second player to purchase the second item.

A game system including a first player terminal used by a first player, a second player terminal used by a second player, and a server device connected to the first player terminal and the second player terminal so as to communicate with each other,

• the first player terminal transmitting, to the server device, an exchange request to exchange a first item owned by the first player for a second item different from the first item,
• the second player terminal transmitting, to the server device, an acquisition request that the second player acquire the first item in an exchange source from the first player,
• the server device comprising:
• a storage unit that stores player information in which each of items owned by players is associated with each of the players;
• a reception unit that receives the exchange request from the first player terminal and receives the acquisition request from the second player terminal after the exchange request;
• a judging unit that judges whether or not the second player owns the second item based on the player information when the reception unit receives the acquisition request;
• and
• an item exchange processing unit,
• when the judging unit judges that the second player owns the second item, that sets the second item owned by the second player as a candidate item to be exchanged for the first item in the exchange source,
• and when the judging unit judges that the second player does not own the second item, that transmits a game image for purchase to the second player terminal, the game image being for allowing the second player to purchase the second item.
