I just bought a Wii U but I don't know what to do with it. I only have MK8.

splatoon
Why don't you try CTGP 8 legacy?
Not many people like the wiiu, so you can find used games 4 relatively cheap -- Zelda breath of the wild, mario 3d world, Zelda windwaker hd & super smash bros, are fantastic games, I've heard great things about splatoon too!
