Abstract: A video game system for playing a game while controlling a movable game object. A player operates first and second steering units 12, 14 with his or her right and left hands to input first and second propulsion vectors for first and second propulsion units in the movable game object. A steering information computing unit 30 is responsive to the first and second propulsion vectors to compute direction and rotation information indicating in how direction and manner the movable game object having the first and second propulsion units moves. These direction and rotation information are output as a steering signal. A game computing means 40 is responsive to the steering signal for computing the game so that the movable game object moves within a game space. This is indicated on a display 44.
