Wario Land (I regret not playing this on Wii but I still think should have been cheaper)
Excite Trucks / Bots / Bike (Wasn't fond of the motion controls but many did, Switch should support both)
Wario Ware (use ideas from the good old versions of gba, ds and wii, use both pointer and motion controls)
Captain Toad (Should become a series really. They could add multiplayer and maybe crossover it with minis from Mario vs DK)
