I am such a fan of DDR, especially when you can play at home with your friends after a couple beers. This is a whole new DDR with new sounds, moves, and grooves. Fantastically fun for all ages.
DDR is fun when you just want to let loose a little bit (though some of my friends who take it seriously would say the opposite). You can burn some calories while competing against a friend, or just challenging yourself. Its a great game- and better when you get a bunch of people in on it.
