A non-limiting example game system includes a processor incorporated within a main body apparatus, and the processor simultaneously controls a player character and a competitive partner character to advance a golf game. The player character is moved, when hitting a ball, toward a next hitting position. During movement, the player character interferes with movement or hitting of the competitive partner character according to an operation of a player. Moreover, when the player character executes a special shot, a shape or a property of a game filed is changed so as to interfere with movement or hitting of the competitive partner character. On the other hand, the competitive partner character interferes with movement or hitting of the player character or another competitive partner character. A victory or defeat of a competition game A is determined based on the time and the number of strokes both required from execution of a tee shot up to a cup-in. That is, a game element is introduced between hitting processing and hitting processing, and the required time affects a victory or defeat of the game.
