My favorite horror game ~ as in, my favorite kind of horror ~ has to be
Unknown Armies. You Did It, after all ~ the beautiful horror of broken people pursuing esoteric means to break or fix or both the world by means of utterly mundane banality is one that just tickles me even pinker than usual.
It's not particularly Hallowe'eny, though. When it comes to the reason for the season, I'd probably hafta say that
Deadlands, especially
Hell on Earth, has to come second to the
World of Darkness (1st edition thru 20th anniversary edition) for me. I was exactly the target market for it in a lot of the ways back in the 90s, and many of the ideas I encountered therein have been embarrassingly influential on who I've become since. I like to run or think of menagerie games, blending in the
Chronicles of Darkness, hoping to build complicatedly deep, incredibly specific, themes by bashing together the various cosmologies and ethics and things.
I've met two of my absolute favorite fan-authors for
In Nomine in very not-RPG settings, one of them the night before last, so it's on my mind. It strikes me that there's plenty of option for horror there, but I don't think I've ever seen that potential quite made use of . . . . I might hafta get on that.
One of my most frequent players has a strong palsy. Dread is great if everyone can participate.
As the child of a mother whose Gillon-Barre affected her hands in such a way that she could never play Jenga, even if she somehow developed an interest in RPGs, thank you for pointing this out.
