The Our Members Page on the PC Gaming Alliance Website now has two recent changes worth noting to the membership of this nonprofit corporation "whose mission is to promote PC gaming worldwide." One is the departure of cofounding member Activision, and on this departure (and apparently others) Kotaku got a response from the PCGA saying: "a few members have decided they cannot justify the budget (membership and staff) required to maintain an active role in the PC Gaming Alliance at this time." Also, Big Download notes the addition of a mysterious new member called Sony DADC. This mystery is solved by clicking the link which leads to the SecuROM Website, so the purveyors of the widely reviled DRM solution are in at the PCGA, but one of the world's largest third-party publishers is out.
