Just Dance 3 and Dance Central is my favorite. I am health enthusiast and make sure I get some exercise every day. Going to the gym is expensive and boring. Just Dance has been exactly what I need for my physical activities.
One of the boys favorites type of games are the dance games. He is in dance class at his school and he figures that is one of his ways that he can practice.
I must say Gunstringer is my favorite. The controls are very intuitive, and the lame jokes make me laugh. Plus the animation style that switches between live video and CGI is really cool.
