In addition to listing the distinct features that made WoW successful, the restrospective provides an overview of its post-launch history, up through The Burning Crusade's launch. Everything from Onyxia raids to the ever-changing PvP Honor system is covered. If you're a hardcore WoW addict, little of it will be new information, but if you're just getting started or a casual user, you'll probably learn a thing or two. See the vid embedded after the break.
