I have played every Just Dance game except for the two Just Dance Kids games (lame), and Just Dance 3 is by far the best. Allow me to explain below.
Story: None. Let's just skip this category.
Gameplay: 10/10 The gameplay was by far the best of all the Just Dances, with the biggest assortment and variety of songs, so all kinds of people around the world know at least one song. The basic idea of Just Dance is that you pick from several different songs, and follow the dancer on screen by way of pictograms at the bottom. This was essentially all there was to the first 3 good Just Dances. This one, however, adds an element of interest for single players as well, which I like a lot: unlockables. You can actually unlock a song: there might be more songs to unlock, but the only one I've unlocked so far is a song I've never heard of called Baby Zouk Zouk. Mostly you unlock different choreographies for other songs, such as Party Rock Anthem and What You Waiting For. There are duets from the past two games and a new feature called Dance Crew, which has four players doing different things. There aren't many of these, the main ones I remember (that people would know) are Dynamite by Taio Cruz and I Was Made For Loving You by KISS. The funniest experience I've had with this was watching my parents and the parents of one of my friends dance to a weird Japanese song (that looked like a spoof of Power Rangers) called Spectronizer. It was hilarious to watch them running in circles and waving their arms.
Music: 10/10 I like the music in all the Just Dances because of the vast variety. There has never been a Just Dance where I know all the songs, because I would have to live about 80 years and speak a ton of languages. The music can please any crowd, whether American, Japanese, African, or Indian (or possibly Spanish).
Graphics: 10/10 The graphics were colorful and smooth, really showing the creativity of Ubisoft.
All in all, this game is great for anyone. BUY IT!!
this game is so fun and easy to get the hang of. we used it at a birthday party for twin 5 year old's and all the kids had fun and exorcized as it was raining and all our party plans changed my 13 year old popped it in and took charge. what a life saver.
