COMMUNICATION GAME DEVICE

A communication game device which is disclosed can communicate with another game device, memorize the information about a communication partner at the time of the communication, and offer the communication game device which can process information for the succeeding game to be reflected in the contents of a game or the simulation. The communication game device has a processing section, a program storage part which memorizes a control program, an image storage section which memorizes character pictures matched with picture IDs, and controlling elements which can be operated by a game player. When the player's game device receives parameters from another communication game device, the parameters are stored or the data is renewed. If a parameter containing a body ID and the same body ID as arbitrary data is not stored, the arbitrary data in the parameter is memorized. If the parameter has been memorized, it is updated.
