From playing the demo on xbl i can say that this is going to be a very fun game.
The gameplay is fast, flowing and compelling.
The graphics are better than the original anime.
The controls take a little bit of getting used to and aren't intuitive at first, but they are very accessible when you get to grips with them.
This game is a sequal to the successful tenkaichi games on the ps2 and wii and is an improvement over them in terms of quality of presentation and the flow of combat.
The demo promises great things, let's hope the game delivers.
