Got all 3. Great mulitplayer fun. If you're looking for an indepth fighter however then this is not it. Most combos are stuff like B,A,A,B,A,A,A,A etc..
Alot of fun with 3 friends. If you're going to get one of them, go with part 3.
Has more multiplayer options then part 2, and the first game was only 2 players.
