Started playing The Blair Witch for PC a while back on my old computer... scary as hell. Never installed it on my current computer, but now would be a good time if I can find it again. Also, never finished Playstation games Blood Omen: Legacy of Kain, Soul Reaver 2, or Blood Omen 2, so I'll most likely give one of those a try again. Oh yeah, and then there's Medievil II... it just didn't pull me in like the first one did, but it's worth giving it another shot this Halloween.

Only got so far in Thief: The Dark Project, too. Though strictly not a horror game, it does have some spooky parts.
