One of the biggest PC gaming developers has said bye-bye to the PC Gaming Alliance. Activision Blizzard has withdrawn its membership, according to GamesIndustry.biz.

What does this mean, really, for the alliance? Well, for starters, they no longer have the biggest MMO or some of the games with the most rabbid followings (Starcraft and Diablo). Not to mention any offerings from Activision.

While the move certainly won’t hurt Activision Blizzard, the PC Gaming Alliance may suffer a bit in how they’re going to push and market PC gaming over the console. We’ve yet to really see anything major come out of the initiative, and that’s likely why companies are leaving.
