This is Halloween 2010

Halloween is a special time for MMOs -- more so than one might think. In the grand scheme of holidays, it's not a particularly important one, but it's a chance for developers and fans alike to indulge in some seasonal bliss amidst a backdrop of monsters and pumpkins. And considering that there aren't many MMO players who dislike dressing up and getting loot from anything, it's a perfect holiday for fans of our peculiar little hobby.

This year has been no exception to the rule. Not only have we seen a plethora of new and returning events, a couple of games that aren't even technically released yet have gotten in on the action. So click on past the break for the rundown of all the holiday events that we've covered or been notified about. You still have a little time to take part if you've been avoiding them, but hurry... these events will likely not rise from their grave again until next year.

	Age of Conan's Night of Lost Souls A trio of quests for Age of Conan offering rather macabre rewards for the players undertaking the challenge.
