In a first game, a training-completed game medium having a first parameter associated with a training-target game medium is generated using an in-use game medium. The second game is played by using the player-selected culture completion game medium. In a case where a training completion game medium having the set first parameter is set as an in-use game medium in the first game, a second parameter associated with a training target game medium is changed based on the first parameter. In the second game, the first parameter is set based on a second parameter for cultivating the completed game medium. 在第一游戏中，使用使用中游戏媒介来生成具有与培养对象游戏媒介关联的第一参数的培养完成游戏媒介。通过使用玩家所选择的培养完成游戏媒介来玩第二游戏。在第一游戏中将具有所设置的第一参数的培养完成游戏媒介设置为使用中游戏媒介的情况下，基于第一参数来改变与培养对象游戏媒介关联的第二参数。在第二游戏中，基于培养完成游戏媒介的第二参数来设置第一参数。
