FG got me thinking
Work in process

Fantasy Horror is a much harder genre to game in than standard horror.

Now Supernatural/ Horror adventure shows (Like Buffy, Angel, Charmed, or any number of action/ adventure stories/ movies/ shows with monsters and magic) have a lot to do with fantasy. They add a fantastical element to background, so anything can happen... as long as it follows 'the rules' established for the setting. 'The rules' become important, as they define what is part of the continuity of the world. If item X works one way one week, and a completely different way another week, the fans would holler and be annoyed... as well as any verisimilitude created by the show would vanish.

Any piece of fiction, and a piece of fantasy even more so, needs verisimiltude. (ed note: ver·i·si·mil·i·tude vr-s-ml-td, -tyd)
n. 1) The quality of appearing to be true or real. 2) Something that has the appearance of being true or real. ) Without it, the piece of fiction fails. Don't believe me? Have you ever read a piece of fiction (not assigned by a teacher) that did not hold your attention? That author did not achieve verisimiltude, making you care about the world or characters. Hence 'the rules' for a fantasy piece become important. We expect fantasies to have elements that are not part of reality. However, if there are variations, we expect the variations to be consistant. So if the Wand of Watoomb does wind magic one episode, we expect it to do wind magic every episode. So once you have defined 'the rules' anything that occurs within those rules is 'okay' or part of that continuity.

This is how supernatural action adventure continues to work. We expect vampires to turn to dust when staked (except for the very rare and explained exceptions), supernatural visions to be accompanied by blinding pain, that three witches with potions can vanquish the source of all Evil... given enough time. If the episodes don't follow the established rules, no matter how silly, there is no continuity/ drama/ and enjoyment, as any damm thing could happen.

Supernatural gaming is the same way. We know that monsters exist, and how magic works, and how we, the characters, are part of the wider world. Even if the characters start ignorant, they become knoweldgable soon. In short, we know the rules.We know what to expect. We understand that magic works.
