Abstract: A game system allows a user to play a game in a similar way to a game machine. The game system includes a server device, a game machine, and a network terminal device. A game machine program makes a control device function as a device for making a user play a game and a device for accepting a predetermined service from the server device as well as identifying a user in cooperation with the server device. The server device is provided with a virtual game machine portion which executes the game machine program and makes a control unit thereof function as the device for making a user play the game and the device for accepting the service. The network terminal device is provided with an I/O control portion which makes the network terminal device function as a remote I/O device for the virtual game machine control portion.
