I'm already running Vaesen on most fridays. I'm tempted to do something boardgamey on Halloween.
My tradition has been, since the mid 90's, to do unhalloweenish boardgames with friends. For reasons I cannot fathom, most of my friends are agnostic or neopagan... halloween themes tend to be either avoided or mocked... well excepting the sky-clad in the woods of a few of them.
