I can't believe there hasn't been a discussion of this game since it was still a Gamecube game! This game is probably the most fun thing on the Wii! Who's played it yet?
Man... This game is so fun. It still has RPG elements, but it focuses more on the platforming aspect. It's a 2d platformer, much like the original mario games, and there are tons and tons of inside jokes.
Anyone who has a wii and does NOT have this game needs to have some sense slapped into them. This is a system seller, for me. I need a wii for this game alone. Only thing I can complain about is... Poor Luigi, he's the butt of a lot of jokes in this game... Luigi was awesome, I always liked him better than mario, but this game makes him out to be really stupid. Oh well...
If you have a wii, go out and get this game NOW! If not, make friends with someone who owns one. And buy this game for them if they don't have it. They'll thank you for it. And you'll just be grateful to have a Wii owning friend.
