Okay, so I'm biased. I'm a dancer and I always have been.Even so, this game is excellent. In my opinion, it's the best release in the Just Dance series to date.You can easily go look up the song list from the games, so I won't waste your time with that. Let me just point out some of the differences between this and previous editions of Just Dance:--Workout Mode: There is no "Just Sweat" to turn on during the normal dances. They've replaced it with a separate workout section where you can choose a 10, 25, or 45 minute workout which consists of several fitness sessions set to music, broken up by songs from the actual game. The songs are selected by the way you move in the fitness sessions: cool or intense. There's also a calorie counter, which is definitely convenient.--Dance Quests: Instead of broad overarching objectives for the game, each song has its own list of goals for you to meet. Once you complete them all, the song selector turns gold. Big improvement, in my opinion.--There's no Simon-Says mode or speed shuffle. Also, shuffle no longer has the option to skip songs. Bit of a downer, but not enough to lower my opinion of the game.--Alternate Versions: Not only can you unlock mash-up versions of the game, but now there are also alternate versions of some of the dances, typically marked extreme--and for good reason! Difficult, but no doubt fun for anyone who enjoys a good physical challege.--Dancer Cards: Ever wonder how good you actually were at Just Dance? Now you don't have to! Dancer cards keep track of everything you do in the game. It logs the time you've spent playing, the calories you've burned in workout mode, your favorite dances, average number of stars, and your dance style. Plus, there's a bunch of fun avatars to choose from. Fabulous update.I think that covers the most significant differences and updates. For the past several weeks, I've played the game every day. Yep, it's that good. Long story short, if you like dancing and you like the Wii, get it.
