They let you put on funny clothes and fly around. A lot of people are into that.
I had my own experience in that 'Game'.
I logged on to see what the fuss was about, got invited to a party somewhere, I still had not mastered the controls (Yes, even simple walking), the Dance owner said "You are bumping in to people, stop it or I kick you"
So I logged out, and deinstalled the software
