Publication number: 20100210360Abstract: When a player character performs an act tendency (boom) triggering act, the act number counters are updated for each non-player character associated with the boom triggering act. The value of each act number counter is periodically added to an act tendency value for each non-player character. After an act tendency value reaches an upper limit, the corresponding non-player character performs an act in response to the act tendency triggering act performed by the player character. The act of each non-player character is changed in accordance with the acts performed by the player character in the game world, which provides the player with a fresh feeling that the act performed by the player character set a trend in the game world.Type: ApplicationFiled: May 3, 2010Publication date: August 19, 2010Applicant: NINTENDO CO., LTD.Inventors: Hajime TAKAHASHI, Gentaro TAKAKI
