Summary Box: 'Battleship' among game-based movies
BETTING ON GAMES: "Battleship" opens in Europe on Wednesday. It gives international audiences the first chance to decide whether a board game-based movie is sea-worthy.
THE IMPETUS: The idea of turning board games into movies has gained new traction in part because of the huge success of "Transformers," and to a lesser extent "G.I. Joe."
POSSIBILITIES: If it succeeds, "Battleship" will be the advance guard of a whole fleet of planned adaptations of Hasbro games including "Ouija," "Risk" and "Candy Land."
