I don't own a PS3, but I wonder, why is the 360 excluded from this discussion?
1. Animal Crossing: Let's Go to the City/City Folk
2. Zack & Wiki
3. Wii Music
4. Carnival Games (I know, I know, I'm so ashamed I can't even bear to add it to my games list, but it was at a bargain price. For the record, its an awful game and not worth what little money I spent on it).
5. Mario Kart Wii/Wii Fit (Got them both on the same day).
