"I think on one hand the Wii has become the most expensive board game on Earth - it's the kind of thing that families will play at Christmas, and probably won't play again throughout the remainder of the year. So things like Wii Sports, Wii Fit to a certain extent, that's great. "
I think it's pretty much true, at least for me.
