My roommate just got this game. And I have got to say it is one of the best games I've played on the Wii. Its looks really cool. The story doesn't seem the most complex, but enough to keep it interesting. and the game play is a hell of a lot of fun. Plus its got lots of blood splattering all over, which is always fun to watch. I have a feeling its going to be one of those games that slides under the radar because of Galaxy and Brawl, but is awesome none the less.
