I would like to get one for our house - exercise for the family and games for the grandson .
Boom Blox is a fantastic game...kinda like Jenga on crack.
i still play on my commador 64 no my wife got me a wii last year (came into a little cash) and we play it with my kids from time to time. its a great system and if you are not into gaming (like halo or something like that) its sweet
I played wii fit at a friend's place. I thought it was pretty crappy, doesn't even break sweat or anything.
The Wii outsells the others by a large margin. That should tell you something right there.
