OMG SO FUN!!!!!!!!!!!!
Granted, these games are very simple in their style. The bodies of the characters are little round ball pieces, but they are so cute it doesn't matter. What is awesome is how easy it was to play! Sure, there was a slight learning curve, getting the hang of the Wii-mote and Nunchuck (for boxing) but once I got it figured out, good times!
I'm a bit of a spaz with the Wii-mote - it's easy to over-compensate. Especially when you're used to the old 1980s kinda motion sensorts that required you to overact to get their attention. But it's really all very intuitive. Boxing was fun as the Wii-mote and Nunchuck were just extensions of your hands so you moved them around to block and punch and dodge. And I won both games (beginners luck)
