Lego RB = GH: Aerosmith = DDR: Disney Mix

All 3 were considered missteps for their franchises. And no, I don't care that some DDR fanboy is willing to waste $100 on Disney Mix on eBay either, it sucks.
With that said, I still love GH & RB, and am looking forward to the Beatles release. DDR, on the other hand... haven't played one since Ultramix 2.
