In a perfect world (at least for the PCGA), those other parties would have been prominent PC publishers. Like Valve, or maybe EA. But no. Instead, "replacing" Activision in the group's lineup is... Sony DADC. You know. The guys who do SecuROM, the overly-restrictive piracy protection software that's been the bane of PC gaming for a while now.
We thought this group was about highlighting the strengths of the PC market, not its flaws.
