Has anyone thought of doing an adventure based on GenCon? I haven't been to GenCon myself, but seeing pictures of it, I can definately see an adventure there. You've got people dressed up to look like characters/creatures of all different types. Any Shadow creatures could "blend" in and the characters could be gamers who find out that some of these "attendees" are truly what they appear to be. There's also all sorts of unusual and interesting things going on. Well known publishers, etc. could be replaced by dopplegangers or controlled by demons or whatnot. What might make it even more enjoyable would be running it at GenCon.
