I bought it yesterday mainly to play Super Mario 3D World (not disappointed) and that's it really but if you love Nintendo franchises then it's a great time to get one.
Mario Kart 8, Smash Bros, Donkey Kong and others all this year with some decent stuff out all ready. It also supports Wii games and is backed up by Virtual Console (currently only NES and SNES games but others in future). You will find some of the best games ever made here.
Despite the negativity towards Wii U, i'm very impressed with the system although gamepad is strange at first.
Xbox One, PS4 and Switch (+ Many Retro Consoles)
