Buying Wii or Wii U?

Buy a Wii U, the original Wii have a pathetic number of good games

Haha, no. Anyone of that opinion shouldn't be buying Nintendo consoles, period. If you weren't happy with what you got on Wii, you won't be happy with what you get on Wii U.

The wii had a ton of excellent games.

All you really need is a Mario Kart.

Sonic All stars racing transformed is better than mario kart 7. Since it looks like they're going to rush mario kart U as well, I strongly disagree.
