A thread on Capcom-Unity links to a preorder listing on GAME.co.uk for Dead Rising 2 that has the Games for Windows LIVE logo on the cover art. The original poster seeks a confirmation, and gets one, as Capcom's Christian Svensson responds saying: "Yes, DR2 uses Games for Windows Live (I don't feel bad confirming that since as you've pointed out, it's on the box)." Thanks TheWeaponeer.
Oh, god, WHY???. Why would you use that POS, Capcom?. Why do all the PCGA cronies make all the wrong decisions and then complain that their games didn't sell because of piracy?.
Go stand in the corner with Ubi's DRM, you idiots.
