This week, Xav gives a heartfelt goodbye to BigDownload.com in his final episode of the BigCast. Joystiq's Ross Miller comes in to talk about Left 4 Dead. TheBBPS.com Editor-in-chief Dan Zuccarelli drops by to shower Fallout 3 with love and Massively's Kyle Horner drops in for all three segments which includes GTA IV problem talk, Mirror's Edge disappointment and more. This is an epic return, clocking in at nearly 2 1/2 hours of BigCast action. They're back, baby! This is the BigCast.
