Dino Crisis (1999)
Silent Hill 3 (2003)
Amnesia: The Dark Descent (2010)

Haven't played many horror games, but the above were both gripping and terrifying to me. Well, Dino Crisis also was fun, so it didn't offer the same level of terror that the two others did, but I remember playing very carefully and in suspense, so I will count it.

slender man is not scary tho so outlast beats it plus the whole gore thing makes it even more traumatizing to some than a blankface skinny entity that hides behind things lol it only messes with a person if they were headphones loudly in the complete dark
RE7 is return to form scary so it keeps the best horror title of 2017

2015 - SOMA

That slow building atmosphere, sound design, and existential dread. This game was tops for me. Maybe not as frightening as Amnesia (which was god damn frightening), but the atmosphere, setting, and ideas were so oppressive. I felt crushed under a weight of pure dread and misery.

Great thread though! Gives me an opportunity to get a handful of scary games to queue up this halloween.

Haven't been playing nearly enough horror games recently. Feels like I need to be in a specific mood to want to play them. Still, there's one game I would like to mention that I haven't yet seen on this thread:

-Spooky's Jump Scare Mansion (A really cool little horror game that does a great job of building up suspense, starting out very innocent and almost kiddy with its cartoony art-style and silly attempts at scaring the player. However, that early silliness is completely intentional, and the further you get in the game the more unsettling it becomes, to the point that those same early weak attempts can now suddenly get to you because you're so tense. Best of all, its completely free on Steam, so there's no reason not to try it out.)
