Fast Racing Neo.
I only bought five games for my WiiU.
Mario Kart 8 (reason I bought the console)
Wii Party U + Nintendo Land. (Both came bundled with the console).
Mario Party 10 (This was a mistake.)
Fast Racing Neo
I played through 3d world with a friend, and dabbled with DK and NSMBU (oh dear), at a friends as well.
