Summary: Either the camera or the game sucks at picking up multiple people. That said, it's a fun game which is great at parties and for bringing friends as well as family together. Good, wholesome, fun. It does the job.
Summary: the suggested songs are pretty annoying and i don't know why anyone would want to dance to slow songs. the dance moves themselves are pretty random and involve a lot of moving around which isn't always a good idea in a small space or a room with a lot of people.
Summary: I have used both Just Dance 2014 on the Xbox and Wii and have to say that the Xbox Kinect experience is much better. MY USE: I use this for cardio exercise. I especially like the World Dance Floor because I am motivated to dance harder and more accurately because I am competing with other dancers.
