MKWii is pretty good. I only play it casually, and can't play online for lack of a network to connect to at school, though I do at home. But I definitely prefer it to Double Dash. The two characters to a kart thing was not my favorite addition, though that was more because I had to choose between the characters who got items I wanted and the characters I actually liked. I mean, Koopa was okay, but if someone more interesting could have gotten the triple shells, I would have been happier. And I do like the new stages in MKWii better too. Best ones since 64 for me.
