The fifth annual BlizzCon took place on October 22-23, 2010 at the Anaheim Convention Center. 20,000 fans of titles like World of Warcraft, Diablo and StarCraft convened, while nearly a million viewers watched from home. The first day of BlizzCon featured costume contests, an appearance by comedian Jay Mohr, and two Blizzard fans even got engaged live onstage. Aw. All images by Christopher Victorio.
