I think this game will appeal a lot more to people on the NDS than it did on the NGC.
4 players with NGC = 4 GBAs, 4 link cables, 1 NGC and having to gather 4 friends at home. Now it's just 4 NDSes, and you can play anywhere, like in class :p. Well, everyone would need the game too, but let's not take that into consideration. :p
