Mariokart Wii is awesome. Buy it now! It’s great fun! The wheel is a really funky addition to the controller, which, whilst not doing anything, does everything 
Super Monkey Ball Banana Blitz would probably be equally fun, if I could control it at all. But I can pretty much make the monkey go off the edge, or roll around until I run out of time.
Sonic and the lost rings (or something) falls pretty much neatly between the two.
Also the Wii is quite disturbing when the blue light flashes on and off.
