Abstract
Game system in which an object is arranged in a virtual three-dimensional space including a display device, an input device for outputting signals according to player operations and a game control device for executing a game according to a program while checking the output of the input device and displaying a visual field image including the object on the display device. The visual field image is viewed from a predetermined view point position in the virtual three-dimensional space. The game control device includes a position determining device for determining whether to view the object from a first view point position which is a back and slightly inclined position toward a moving direction of the object to view an observation position set forward the object, or from a second view point position from which the observation point is viewed in a fixed direction regardless of the movement of the object.
