CSM Writes:
"In addition to the standard dancing mode, Hottest Party 2 contains a dance trainer mode which teaches gamers how to do some of the moves they see the characters do onscreen. Keeping up with the Wii's trend of getting people more active, a workout mode is also in the title. This allows you to set targets for amount of calories burned for a particular session, and the game will track your progress as you play.
For those who own the first Hottest Party title but have had a tough time unlocking all the songs and areas to dance, there is an option in Hottest Party 2 that allows you to open all items in the first title, however you will still need to own the first game on disc."
