Not a silly question. Here's my take. Wii Fit is pretty broad reaching with lots of games and things to do, and also pretty pricey. Wii Active is basically a fitness regimen that you can tailor to you. Bob Greene, Oprah's famous trainer is the source of the information, and then you pick a trainer who demonstrates the exercises and then coaches you through doing them correctly. At the end of your workout it tells you how many calories you burned and how that compares to the projected amount. (the harder you work the more you burn, and so far, I've surpassed the projected amount every time.) I think the Wii Fit has more choices, but for what I needed the Wii Active is perfect.:thumbup:
