Abstract: Systems and methods for providing a celebrity chase virtual world game are disclosed. In the virtual world game, users compete against programmed game logic and/or other users to collect autographs and pictures of virtual celebrities for game credits. Various game mechanics enable a player to disable an obstructing avatar, or to impede another player's progress. For example, one player may use a virtual camera flash to temporarily blind a bot trying to block their path toward a virtual celebrity, or use it on another player, during which the programmed avatar and/or other player is impeded from pursuing the virtual celebrity. In other instances, the impeded player may continue to navigate the virtual world, but be prevented from pursuing the virtual celebrity for a predefined duration of time. Once a virtual celebrity is captured by a player, the player may collect a virtual autograph and “selfie” picture with the virtual celebrity.
