I think that this is going to be a great game for the wii. I liked the older ones on the ps1 and I think this one is going to be just as good. I hope they add every character in the show.
I've always liked the DragonBall Z games but I'm not too certain if it should use the controllers capabilities or not. I wouldn't image how the game would use it.
I read in a article on ign (or was it the e3 website?) that the new DBZ game will be using the wiimote and the nunchuck as controls. It also said that vairious moves are executed by twisting and moving both the controls, and that randomly swinging the controlers around wildly will produce little results. Idk how that is meant to work but it will be a very unique fighting game nonetheless.
