According to ESRB, this game contains: Animated Violence
Parents wont find anything objectionable in this game well, maybe the sight of the always scantily clad Cammy.
Arcade action game fans will likely want to rent Cannon Spike first. Its high difficulty curve will likely put off the casual fans and could appeal to the hardcore.
Dreamcast owners may want to hold onto to this game if only for the sake of novelty. Who knows when Capcom characters will be thrown into one game outside of the next Street Fighter sequel?
Multiplayer fans could find a decent playing experience but don't expect to go far on the higher difficulty settings.
