Patent ID: 7901293

Claim:
A game system comprising first and second game apparatuses which carry out a game process for each predefined process cycle of a predetermined length, the first and second game apparatuses communicating with each other in a multiplayer game play, wherein the first game apparatus includes: a first timer; a first timing information acquisition section which acquires first timing information, which indicates a timer value of the first timer at a predetermined reference time in a process cycle of the first game apparatus, said timer value of the first timer corresponding to a count value of a first counter within a predetermined range, said count value of the first counter representing timing to start each of repetitive processes of the game in the first game apparatus, and a first timing information transmission control section which transmits the first timing information to the second game apparatus, and wherein the second game apparatus includes: a second timer; a first timing information reception control section which receives the first timing information from the first game apparatus; a second timing information acquisition section which acquires second timing information, which indicates a timer value of the second timer at a predetermined reference time in a process cycle of the second game apparatus, said timer value of the second timer corresponding to a count value of a second counter within a predetermined range said count value of the second counter representing timing to start each of repetitive processes of the game in the second game apparatus, a detection section which detects a difference between the predetermined reference time of the second game apparatus and the predetermined reference time of the first game apparatus, based on the second timing information and the first timing information received by the first timing information reception control section; and a first cycle change section which temporarily lengthens the process cycle of the second game apparatus if the difference detected by the detection section is equal to or more than a predetermined value, to cause a length of the process cycle of the second game apparatus to correspond more closely to a length of the process cycle of the first game apparatus, wherein each of the first and second game apparatuses further includes a display control section which designates a display position based on the count value of the first or second counter, respectively, and updates a screen display corresponding to the display position.
