I thought it was just OK, but admittedly I didn't play it much, or know what to expect. At first you're just jogging (in a completely unnatural way) and doing these log jumps. Perhaps I missed something, though? It's not my game - I just played it at my friend's house.
Re: has anyone tried the Jillian Ultimatum 2009 Wii game?
I don't think it sucks. I think most of the people that I have seen reviews from are video game geeks who are complaining about the graphics.
It is a way better work out than normal WII Fit. I actually find it difficult.
