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.
