Plenty of development companies out there make videogames on a yearly basis, and have hardcore fanbases to boot. However, not many developers out there are as dedicated to serving their fans' needs, and in such a quality manner, as Blizzard.
Their dedication, hard work, and growing fanbase is what keeps them alive and thriving. And 2009 looks to be only strengthening their already incredible place in the PC gaming world, and the technological world altogether.
With sequels to their biggest franchises in the cooker (StarCraft II, Diablo III, etc.), 2009 is already turning out to undoubtedly be.... The Year of Blizzard Entertainment.
