I wonder if the PC version will be Steamworks with Social Club layered on top. I'd long assumed this would be the case, but GMG's product listing mentioning "Other DRM" has me a little doubtful. It wouldn't make sense for R* to stick with GameShield considering A) It sells the Steam versions of its games literally everywhere but GamersGate, and B) GameShield doesn't protect against "day zero" piracy.
