Halloween is a great nerd holiday, and it extends into Massively Multiplayer Game space. Everquest Live is offering up a series of events from the Kithicor Forest to the Hafling village of Rivervale. EQ2 has trick or treating in the two major cities, as well as smaller quests elsewhere. World of Warcraft players can also trick or treat with Innkeepers to honor the holiday of Hallow's End. Fashion seems to be the primary motivator in Anarchy Online's holiday event, which allows you the chance to snag Halloween themed t-shirts. Guild Wars has the winners from a Halloween art contest, as well as some theming in-game. Finally, Final Fantasy XI's always terrific seasonal events continue with The Harvest Festival. FFXI and World of Warcraft specifically allows you the opportunity to dress your character as various monsters and characters. My priest made a great pirate. Arr!
