I owned a wii u what a waste of money. I traded mine in for my ps4. The games on it are just lame. Mario ZzZzZ it's pretty much the same as every other mario game. Luigi u is basically just an addon, More of the same boring stuff. Never liked Zelda. Scribblenauts? Can Get on other consoles. Snore. Monster Hunter seemed ok. Just dance. Available on other consoles. Not interested. Batman and tekken also on other consoles. Super Smash Bros... boring. I loved the gamecube smash bros. The wii version was boring, I hold little hope for a wii u version if that's even slated. There is just nothing worth my money on wii. That said I can't recommend ps4 either as the launch games are not stellar either.
Totally hanging out for kingdom Hearts 3. It was that game alone that sold the ps4 for me
