How about a Game Center location game, where players earn points for every map location correction they make to the iOS 6 map? (But lose triple points for every correction that's in the wrong direction after each Apple map update.)
Maybe also give bonus points when any location correction is up-voted by randomly chosen 2nd players (randomized to prevent organized collusion) in the same region?
