In a game device (200), a storage unit (201) stores a position of a player character, a position of an enemy character, and candidate positions for new enemy character appearance. A measuring unit (202) measures an elapsed time from the start of the game. The calculating unit (203) calculates a reference distance for determining a position where the new enemy character is to be produced based on the elapsed time measured by the measuring unit (202). The reference distance monotonically increases with respect to the elapsed time measured by the measuring unit (202). When a new enemy character is to be produced in the game, an appearance setting unit (204) selects from among the candidates stored in the storage unit (201) the candidate having a distance to the player character that is closest to the reference distance, and sets the selected position as the appearance position of the new enemy character. |
