NETWORK GAME SYSTEM, CONTROLLING METHOD FOR NETWORK GAME SYSTEM, GAME DEVICE, CONTROLLING METHOD FOR GAME DEVICE, AND PROGRAM

PROBLEM TO BE SOLVED: To provide a network game system which suppresses an increase in the traffic of a communication network, and can share the positions and the postures of objects being associated among a plurality of game devices. SOLUTION: This network game system includes a first fundamental position selecting means, a first fundamental position transmitting means, a first fundamental position receiving means, a second fundamental position selecting means, a self object position determining means, and a self object posture determining means. In this case, the first fundamental position selecting means selects one from among a plurality of fundamental positions which are set in a virtual space. The first fundamental position transmitting means transmits the fundamental position selected by the first fundamental position selecting means to other game devices. The first fundamental position receiving means receives the fundamental position transmitted from other game devices by the first fundamental position transmitting means. The second fundamental position selecting means selects one from among the fundamental positions received by the first fundamental position receiving means. The self object position determining means determines the position of the object associated with the game devices based on the fundamental position selected by the first fundamental position selecting means. The self object posture determining means determines the posture of the object based on the fundamental position selected by the second fundamental position selecting means.
