On the Wii? Not much. I guess my favorites was Skyward Sword and Super Paper Mario. But I have a lot of trouble with the Wii where my games decide not to work anymore for no apparent reason.
Well, I guess you could say that I like Mario Kart Wii, Animal Crossing: City Folk, Super Mario Galaxy 1 & 2. Other than that, not much. I do plan on getting Super Smash Bros. Brawl for my Wii. (Also, you could use a title change because I was not expecting just Wii games in general.)
