Abstract: In a game system which may keep players interested in two or more games for a long time, a first game control server stores game result data transmitted from a first game device in a first data storing section. Then, the first game control server generates first usable data based on the newly stored game result data, and stores the first usable data in a data storing means of a first usable data transmitting section in which the first usable data are ready for transmission. Upon receipt of a transmission request command from a second game control server, the first game control server transmits the first usable data to the second game control server. Each player may execute a game program using the data obtained from a previously executed game and other usable data transmitted from a different game device.
