There are plenty of games about ghosts and ghouls and other scary creatures. Some of them have creepy or gory artwork in them, and a few will make you distrust your fellow players (at least within the context of the game). Of course none of these things actually makes anyone feel genuinely afraid. But when you have to get up in front of your friends and sing or mime or make something up on the spot, it can be very frightening indeed. Do we have anything to fear other than fear itself?
