Just Dance Wii 2 (also known as ジャストダンスWii 2) is the second game in the Japanese series following Just Dance Wii. This game is built in the style of Just Dance 3, but lacks some of its features such as unlockable songs and the shop. Like in Just Dance Wii, song lyrics are highlighted light blue when a male is singing and light pink when a female is singing, or if both a male and a female are singing. This game also includes Breakdown Mode, where the player can skip back and forth through a song in order to learn it better.
Ubisoft didn't change conditions for getting medals, so if your game is hacked, and your game is switched to English language, you can see that some of the medals and thier directions for getting them for them aren't changed.
For example, one of the medals needs Boogie Wonderland to be danced to get it, but the song doesn't appear in the game.
