Cooking Mama: World Kitchen would be first, followed by Wii Fit Plus and Link's Crossbow Training, respectively
Scratch that, I guess my top 3 would actually be Mario Galaxy 1, Galaxy 2, then Wii Sports Resort, respectively
Wii Sports Resort, plus Star Wars The Clone Wars Republic Heroes (I know a lot of people hate that game but I like it, ok? Please don't hate on me.), Wii Sports, and MarioKart Wii. I also like Star Wars Rogue Squadron II and III although they're technically Gamecube games played on the Wii's Gamecube emulator.
1. Mario Galaxy (although I've only played it in 3D all stars for the switch)
2. New Super Mario Bros Wii
3. Mario Kart Wii
(I know it doesn't have to be only mario games even with those my top 3 stays the same)
