I don't have this yet and I'm not sure I'm going to get it. Did you get it when it came out? It's just a game without the balance board. I guess it's supposed to have more than the Wii fit on it. How much do you play it?
I'd pass on this one if I were you. We got it when it came out and didn't play it much. It's supposed to be a sequel to the first Wii Fit, so yes, it requires the balance board.
I bought it when it first came out and I used it all the time. It was cool because it was an addition to the Wii Fit. I don't use it much anymore though. I would say pick it up though, it's cheap now.
