To provide a game device for allowing a game player to relatively readily control an operation target player character object so as to make a motion according to a moving speed of the moving body object. The present invention relates to a game device for displaying an image obtained by viewing, from a predetermined viewpoint, a virtual three-dimensional space where an operation target player character object and a moving body object representative of a moving body are disposed, and providing a sports game using the moving body. An object control unit (74) controls an operation target player character object so as to change the position and posture thereof in accordance with a moving speed of the moving body object according to a result of determination as to whether or not the positions of the operation target player character object and the moving body object satisfy a predetermined position condition.

A video game method and apparatus provides a video soccer game between two soccer teams. A game player of the video game operates a manual controller with a directional controller and a non-directional controller to control a player's game character of one of the soccer teams. In the video soccer game, it is determined, in response to operation of the non-directional controller, whether the player's game character is positioned in front of, on the side of, or behind an opponent game character carrying a soccer ball and belonging to the other soccer team. The player's game character advances toward and automatically tackles the opponent game character to capture the soccer ball depending on the detected relative position between the game character and the ball.
