Claim:
A game system which includes a plurality of game machines and at least one server device connected thereto over a network to enable players of the plurality of game machines to play a two-person game, wherein the server device includes: an acquiring means for, among a predetermined number of character cards each associating a game character with an ability value indicating an ability in fighting motion, acquiring type information on the type of a character card presently used in a two-person game for each game; a conversion-value calculating means for calculating a conversion value as result data for narrowing the difference of the ability values corresponding to the types of character cards according to the type of the character card and an amount of the acquired type information; and a transmitting means for associating the conversion value according to the type of the character card with each character card and transmitting the conversion value to all the game machines, and the plurality of game machines each include: a display displaying the image of a game character appearing in a two-person game; an operating member receiving an instruction for a virtual fighting motion played by the game character in the two-person game; a reading means for reading type information from each character card used in a game; a communicating means for transmitting the type information read by the reading means to the server device; an ability-value storing means for storing an ability value, corresponding to the type information; a conversion-value storing means for storing a conversion value transmitted from the transmitting means; an ability-value calculating means for converting the ability value corresponding to the type information of each read character card into a new ability value using the conversion value corresponding to a character card presently used; and a controlling means for allowing a game character to play a fighting motion given by an instruction from the operating member using the ability value obtained by the conversion; wherein the ability-value storing means stores the ability value of each game character in association with the type information of a character card; and wherein the ability-value calculating means converts to a new ability value using the ability value of a game character corresponding to the type information of a character card read by the reading means and the conversion value.
