My wife went out of her way to finally get me a Wii and I love it! I wanted one at launch, but I didn't feel like being shot for one so we waited.
Anyway, I haven't played anything other than WiiSports, and for right now I'm more than happy to play them. I found out that in one night my wife surpassed me in bowling, which I'd been working on for days. But I love that we can both play, and its hilarious to watch the kids jumping and bouncing around the room playing. Its nice to see them playing a video and not just sitting there mashing buttons. I know its not all that beneficial as far as exercise, but I know after 3 rounds in the ring boxing, I'm usually actually breaking a bit of a sweat(I'm outta shape, deal with it).
Anyway, I'm glad to be part of the ranks. Play on!
