Penny Arcade posted a joke about Figureprints driving people back to play WoW, but today's commentary (by the always insightful Tycho) shows that it wasn't just a joke-- the PA guys have sold their souls back to Blizzard. The game has changed a lot in the past few years, and I admit-- going back to play my Hunter, which I've been doing lately, has made the game almost completely new for me. From all the talent changes to all the new items and the midgame updates, it's almost a brand new Azeroth for anyone coming back to the game.
PvP Online, another popular webcomic, has been running a "return to WoW" comic series as well-- 'tis the season, apparently, to come back to Azeroth. Besides all the changes and the new content, the only other reason I can think of is that there's not much else out there in terms of really established MMO experiences-- everybody else is still getting up to running speed when most WoW players already know what they're doing and how to do it. Are we in the middle of a World of Warcraft cultural resurgence right now?
