Edge has a preview of the upcoming (and controversial) WiiFit.
Wii Fitness is a simple concept executed very well, and the fact that it angered some of the gaming world at its announcement is more an indictment of the industry than an understanding of how it can change the way non-gamers see consoles.
It should be interesting to see how “gamey” the title ends ups being… (i.e. the ski jump game, which I love).
