Haha, I know I'm gonna get flamed for this, but I play DDR. I'm not like the hardcore goth kids (sorry if you're one) that hang out at the arcade all day and play, just every once in a while I'll play. I like music and i guess its a good workout, so hey...why not? I also play beatmania, its the one with the 7 keys and turntable and the notes fall down, just like guitar hero, without the guitar.
here's a vid from about a year ago of me playing ITG (in the groove)...it's like DDR but harder and more fun. I'm on the right.
