Abstract: 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.
