I have both of the Just Dance games. The second one isn't as great. The first one keeps me sweating, but having fun at the same time! I definitely recommend it. =)
I have the first one and I love it, I am a 14 year old and i some what like my video games and like being inside so this is great! I can even get my dad do dance with me some times. I definitely recommend it!
I really liked the Just Dance games. I personally like the second better than the first. The Zumba game is also a lot of fun if you are looking for a dance type game.
