I love the just dance series it's a great workout while having fun. Great songs.

Picked this game up super cheap for my kids. They love playing this game together! Tons of songs to choose from, so you don't need to keep dancing to the same ones over and over.

Oh my goodness, if you liked Just Dance 2 or Just Dance 3, you will be blown away by Just Dance 4! I rented it from Redbox recently and we played for hours. Of course, I immediately bought several copies for Christmas to keep and give out.

The graphics are fantastic, the game rewards you for different levels of achievement (ie. not just the top scorer gets props), and the workout side "Just Sweat" is a million times better than before.

I also own Wii Fit and I can definitely say that Just Sweat on JD4 is the best workout yet. In earlier versions (and on Wii Fit) you have to design your own workout with not so much help from the game. JD4's version has workouts by genre - eg. latin dance, electric cardio, '80s dance, etc etc. You can also choose different workout lengths (10, 25, or 50 minute versions). It also counts calories (though it doesn't ask for your weight or age so that approximation should be taken with a grain of salt) and measures your energy levels based on how hard you're working out to determine if the next song will be higher or lower intensity. There is even a warm-up in the beginning and stretches at the end.

The only critique (as I've had for earlier versions) is that I wish it came with more songs, but those are easy to buy through your Wii console if you have the points (2000 pts usually costs about $20 and available online or as physical gift cards at Best Buy, Walmart, etc; each game usually costs 300 points).

There is just so much to Just Dance 4 that I'm seriously thinking of giving it to my kids before Christmas just so I can play it too :)

Buy it. Seriously, right now.
