I worked at Blizzard for close to three years. During my time there I saw a lot of big things happen: the closing of the Console Division and shelfing of Starcraft Ghost, the launch of the first (and second!) World of Warcraft expansion ... and one that some people say is the biggest event in Blizzard's history, Vivendi Games' merger with Activision.
The merger was, of course, a controversial move; and, like any corporate maneuver, it's generated a lot of misunderstandings, misreporting, misinformation ... in general, it's been a flurry of mis-es. It's upsetting and frustrating to see so many people not understand what the merger means and, in turn, form stubborn opinions.
If you want to help curb ignorance and misunderstanding regarding what's going on with the merger, you're in luck. My former employment at Blizzard means I have a lot of information to share to set the record straight. Even if you're going to continue believing that Blizzard is somehow dipping in quality or in a bad way because of the merger, at least read what I have to say. It'll be worth it.
