An anonymous reader writes with this quote from PC Authority:
"Ever since Microsoft turned its back on Windows gaming in favor of the closed Xbox ecosystem, the platform has been crying out for a champion. The company occasionally gives nods toward a revived focus upon PC gaming, most recently with yet another relaunch on Games for Windows Live and a trio of upcoming PC games, but when it comes to throwing cash around the Xbox is the beneficiary. What can definitely be said is that the one group that should be championing the PC, the PC Gaming Alliance, is going backwards. In 2009 the group lost the biggest PC game developer/publisher, Activision-Blizzard, and now it seems that both Microsoft and Nvidia have bid the alliance farewell."
