^idk what kind of games you enjoy but i think you're missing out. the wii u has some very FUN games: Splatoon MK8 Smash Hyrule Warriors.
I mean I'm not really into those games. The ones that I really liked to play on the Wii was the sports games. I liked being able to play against my friends on that. Otherwise the only other games that I really have loved are the first person shooter games.
yeah, other than Splatoon you may not need a wii u.its insanely fun, but idk if its worth buying a wii u just for one game
