As a fan of crossover games I was pretty excited when they announced a US release for this game. It has so many characters from 3 different companies, some of which I've never even heard of until this game. It's got quite a fun battle system and an interesting story that keeps you guessing and wanting to play on to find out what happens next. I highly recommend it for crossover fans, strategy/tactics fans, and just about anyone who's looking for the next big game for their 3DS.
I came into Project X Zone thinking it would be the ultimate crossover game, but was disappointed. The game was overall boring. The story was dragged on for way too long, and the same can be said for the battles. Story was also pretty lame, taking a pretty good portion of the game for the story to go anywhere. But I can say that the character animation is pretty cool, and landing powerful blows can be very satisfying. But that doesn't save it from boring gameplay. You'll spend the entire game rapidly pressing the A button and moving the circle pad around. I can understand why some people like this game, but it's not for everyone.
