I love the rhythm boxing and the step - I have so many games still to try on the original game, I am noit sure when I will buy an new game for the Wii Fit.
I also just bought the work-out game with Jillian from the Biggest Loser - plan on staring that one this evening -
Don't get your hopes up on this game....we bought it at Best Buy for like $39 or something and a few weeks later after playing it like twice we put it up on amazon and luckily got most of the $$ back. If you don't care for the actual Wii Fit game Jillian's game won't blow you away at all. It was pretty obvious it was VERY cheaply made. Should have been $19 at the absolute most IMHO.
