To provide a network game system for switching a server-client machine without deteriorating the excitement of a game. A network game system () causes each of a plurality of game machines () to operate as a client and at least one of the plurality of game machines () to also operate as a server, thereby providing a game to be played by the players of the plurality of game machines (). A game play evaluation value calculation unit () calculates a play evaluation value corresponding to each of the plurality of game machines () during a game. In the case where a predetermined switching determination time arrives during the game, a server switching unit () switches the game machine () operating as the server from the game machine () currently operating as the server to another game machine () of the plurality of game machines (), based on the evaluation value calculated by the play evaluation value calculation unit ().

Network game system, game machine, game machine control method, and information storage medium

Provided is a network game system for providing a game played by players of game machines by operating at least one of the game machines as a server, in which: the game machine to be operated as a server can be appropriately selected; a measuring unit () of each of the game machines () measures a time required to exchange predetermined data between the game machine () and another game machine () of the game machines (); and a server determining unit () determines at least one of the game machines () as the game machine () to be operated as the server according to the results of the measurement by the measuring units () of the game machines ().

To provide a network game system capable of switching a server-client machine, while avoiding deterioration in the excitement of a game. A network game system () causes each of a plurality of game machines () to operate as a client and at least one of the plurality of game machines () to operate as a server. In the where a switching determination time arrives, a switching determination unit () determines whether or not to switch the game machine () operating as a server from the game machine () currently operating as the server to another game machine () of the plurality of game machines (), based on the play evaluation value corresponding to each of at least one of the game machines (). In the case where it is determined not to switch the game machine () operating as the server from the game machine () currently operating as the server to another game machine, a switching determination inhibiting unit () inhibits a switching determination unit () from making a decision during a period before a given switching inhibited period elapses.
