To provide a method for controlling a game by which the image of teams can be kept and the balance between the teams can be maintained.

The game is played between teams which are composed of different users' characters established by a plurality of users. The number of teams, the total number of characters making up the teams and initial characters making up the teams are predetermined. The users' characters established by the users are inscribed in the system and specified characters of the initial characters making up the teams and/or a specified number of characters smaller than the total number of the characters making up the teams can be replaced with users' characters.
