Halloween is probably second only to Christmas in terms of holiday popularity. Ask just about anybody what their favorite holiday is, and they'll probably list one of those two (if it fits the culture). Naturally, as MMO players, we have fun celebrating it in our virtual worlds just like we do in the real world. And boy, this year, do we ever celebrate. Just about every active MMO out there had (or has) something going on. The 2009 lineup included:

Final Fantasy XI - Harvest Festival City of Heroes - The Deadly Apocalypse EverQuest II - Nights of the Dead Fallen Earth - Days of the Dead Warhammer Online - Daemon Moon Rising Aion - Harvest Revel Guild Wars - The Mad King's Revelry Runes of Magic - Pumpkin Festival Lineage - Cavern of Chaos Lineage II - Spooks and Scarecrows Age of Conan - Nights of Lost Souls EverQuest - The Haunting of Norrath Legends of Norrath - Brraaaaaainss! Star Wars Galaxies - Galactic Moon Festival Exteel - Hey, sweet! Paint! Free Realms - Super Spooktacular Champions Online - Blood Moon Most of these events last a few days into November, so if there's any one in particular you're dying to experience, you might still have a chance if you have a subscription laying around. If you're not able to visit any of these in person, we have screenshots from many of these events in the gallery below. Enjoy!
