To provide a game device and an information storage medium capable of improving the virtual reality feeling of a player and realizing real simulation.

The forward inclination posture of the player 1092 is detected by a forward inclination posture sensor 1072, and based on the operation information of the player including detected forward inclination posture information, game computation such as the control of a moving object 1100 on a screen or the like is performed. Based on the forward inclination posture information, force (whirly torque) for rotating the moving object, the speed (air resistance coefficient) of the moving object and the motion of a character are controlled. In the case that the player takes the forward inclination posture at the time of the travel start of the moving object, the acceleration force (driving force, acceleration performance) of the moving object is enhanced. The force for contributing to the rotation of the moving object and the force for contributing to the translation of the moving object are turned to the force of different systems. A distance from a player is detected, and based on the operation information including detected distance information, the game computation is performed.
