It is awesome! The champion mode was eh in my books. It is a story mode where you play through the career of "Andre Bishop". It is cool, a few good twists, but I would have liked it more had I been able to put my own character in it.
I just do legacy mode. It is awesome. The fighting is very good. Combo's are easier to throw. Training is more fun than it was in earlier years in my opinion. I love the game.
I haven't tried online yet though.
