Game system, game control device, and information storage medium

A game control device comprising at least one processor configured to:

• perform control relating to a game in which at least one game object is selected from a plurality of selection candidate game objects, as a game object to be associated with first user identification information, based on predetermined lottery processing and the selected game object is associated with the first user identification information;
• and
• set a game object as one of the plurality of selection candidate game objects, wherein the game object is associated with second user identification information, and the game object is a game character trained by the second user or a game item upgraded by the second user, and the second user is identified by the second user identification information;
• wherein the game object is a game character,
• the game character associated with the second user identification information can be associated with each of a plurality of pieces of user identification information other than the second user identification information,
• the game character is made available for use in a plurality of games respectively played by a plurality of users identified by the pieces of user identification information, in a case where the game character associated with the second user identification information is associated with each of the pieces of user identification information, and
• the at least one processor is further configured to associate a reward with at least one of the pieces of user identification information or the second user identification information, in a case where the game character associated with the second user identification information is associated with each of the pieces of user identification information and information relating to the performance of the game character in the games respectively played by the plurality of users satisfies a predetermined condition.

A non-transitory computer-readable information storage medium that stores a program for causing a computer to:

• perform control relating to a game in which at least one game object is selected from a plurality of selection candidate game objects, as a game object to be associated with first user identification information, based on predetermined lottery processing and the selected game object is associated with the first user identification information;
• and
• set a game object as one of the plurality of selection candidate game objects, wherein the game object is associated with second user identification information, and the game object is a game character trained by the second user or a game item upgraded by the second user and the second user is identified by the second user identification information;
• wherein the game object is a game character,
• the game character associated with the second user identification information can be associated with each of a plurality of pieces of user identification information other than the second user identification information,
• the game character is made available for use in a plurality of games respectively played by a plurality of users identified by the pieces of user identification information, in a case where the game character associated with the second user identification information is associated with each of the pieces of user identification information, and
• the program further causes the computer to associate a reward with at least one of the pieces of user identification information or the second user identification information, in a case where the game character associated with the second user identification information is associated with each of the pieces of user identification information and information relating to the performance of the game character in the games respectively played by the plurality of users satisfies a predetermined condition.
