I did ages ago. I'm anxiously awaiting my digital koala.
I've only just seen what this game is and I already know I need it in my life. I'd have to buy a USB dance pad too though.
I played this at Pax last year and it was a TON of fun, glad to see it is getting some love .
Also, I just beat Second Son...so good. I cried a few times, that doesn't happen with games very often anymore.
