I bought it, and sold that shit after Randy kept running his mouth about Valve...so that helped reduce the 360 numbers...lol.

Did you know that Gearbox developed some of Valve's older games?

Yeah...that's kinda how Gearbox got started, isn't it. 

so he's the bad guy for calling out to Valve to make PS3 games ?
