I've owned the Wii U again for roughly 2 months and here are all the games I own:
Xenoblade Chronicles
Xenoblade X
Metroid Fusion
Metroid Trilogy
Nintendo Humble Bundle games
Mega Man 7
Lego Jurassic World
Star Fox Zero + Guard (I just bought them again because I missed SF Zero)
Donkey Kong Tropical Freeze
Mario Tennis Ultra Smash
Zelda Twilight Princess
Wii Fit U
Just Dance 2016
Kirby and the Rainbow Curse
Mario Kart 8
And there's also a chance I'm forgetting something.
