Communication game system, game control program and memory medium

A communication game system comprising a plurality of game machines and a network for connecting said game machines with one another, each said game machine (one game machine, hereafter) comprising:

• a virtual space generating means for generating a virtual space in which a plurality of objects exist,
• an input means for inputting movement input information which causes movement of said object (corresponding object, hereafter) corresponding to said one game machine in said virtual space,
• a position information obtaining means for obtaining position information of other objects (opponent objects, hereafter) corresponding to other game machines (opponents' game machines) than said game machine, from said opponents game machines,
• a position information calculation means for calculating a position information of said corresponding object according to said movement input information,
• a position information transmission means for transmitting said position information of said corresponding object to said opponent game machines,
• a distance calculation means for calculating distances between said corresponding object and opponent objects, according to said position information of said corresponding object and position information of said opponent objects, and
• an information volume calculation means for calculating necessary information volume of said position information of corresponding object to be transmitted to each said opponent game machine, according to distances between said opponent object and opponents objects,
• wherein said position information transmission means transmits said position information by said necessary information volume to said opponent game machines.
