I've started to DDR again because I've been getting over weight due to lack of exercise. I borrowed DDRExtreme just to see how it is and so far I like it. Unfortunately the music isn't as good but I do like the Exercise Mode. Previous DDR's had Exercise Mode as a separate section in the game where it would count the calories burned but did not progress in the Game Mode at all. In Extreme, you turn it on and then play Main Game. When you finish a song the calories burned will be displayed under your grade of that song. If you wish to view your daily, overall and progress stats just go to Exercise Mode in the main menu again. This adds a little extra bit of a challenge to the Main Game as you try to beat previous high records of calories burned on that day. To anyone looking to lose a bit of weight and enjoys DDRing, I'd recommend it.
