I have not tried the fit game but used the fit board with our Wii ski game. The more lessons you take the more you can open things up like new ski wear etc. Below is a photo of the hubs and I taking a "photo op" in the game in our Kimono ski wear. Crazy cause I would never wear tabi socks and flip flops skiing!
The Wii is possibly one of the coolest things ever invented. Got to go finish watching Lost now.
