I did! Got the 360 version an hour ago. Gonna start on it in about 30 minutes.
Got it from Wal-Mart with the free copy of Arkham Asylum Game of the Year Edition. I already have the original on PS3 and 360 but a free game is a free game. And since I got the 360 version used from Gamestop, I can trade it in for 100% of the price if I do so within two weeks. Dance Central 2, here I come!!
