Next year though...I want to make a whole day of horror-themed gaming!
Play board games (Arkham Horror, Last Night on Earth), play D&D (I have Cage of Delirium prepped) or terrorize my players with a Call of Cthulhu game, and watch a movie (maybe Dawn of the Dead, 28 Days Later, Evil Dead 2, etc).
I attempted to run a streamlined version of Ravenloft's old A Light in the Belfry adventure with 3.5E. But alas, it just couldn't fit into a single session. Not even close.
Here's to hoping 4th Edition will make everything faster!
