As far as I know, as long as you have a Wii console all you need to buy is the Wii fit game. I found one yesterday at Walmart for $89.74. What i bought came in a long triangular box which included the Wii fit step board, and the actual game that goes into the Wii fit console. They had an extra Wii fit board carrying case that you could buy, but i passed on that. My 17 year old daughter just assured me, that this is all that you have to buy as long as you have a Wii console. (The game i bought is for my 14 year! She better not tell her what i bought her! lol)
