A communication game system includes a plurality of game apparatuses which can be communicated via a network and functions as a parent machine and as a child machine, for example. In the child machine, a moving track of an object to be operated is obtained in response to an input with a pointing device by a player, and transmitted to the parent machine. In the parent machine, a movement of the object is controlled by the moving track, and drawing information to draw a virtual game space including the moved object is transmitted to the child machine. In the child machine, a game screen including the object to be operated is generated and displayed on the basis of the received drawing information.
