Your favorite horror game ?

Amenisia the dark descendent

Slender

Gabriel Knight series, System shock series, Condemned, Silent Hill series and such

Hm, haven't played many. Does Saya no Uta count? Not a Steam game or a "game" by most standards, but it's my personal favorite.

Silent Hill 2 and Cry of Fear (HL1 mod). Both have amazing atmosphere and great story.

I'm not sure, maybe Doom 2

Don't know if penumbra games count as horror but I quite enjoyed them.

Penumbra games

My favorite is Condemned: Criminal Origins, the scariest i ever played is Amnesia.

Fear series and of course The suffering xD

I like Resident Evil 1-4 quite much. I don't know if most of you would call it a horror game, but I think Devil May Cry (the first one) is really creepy at some points. I think DMC is like a more action-packed version of Resident Evil, with demons instead of zombies. :3

amnesia and silent hill :)

It's hard to pick one. Silent Hill 2, Amnesia, Condemned, fatal frame, forbidden siren are my favs

Silent Hill 1

Amnesia, Silent Hill 2, Silent Hill, Fatal Frame 2, Kuon, System Shock 2...

metro 2033

I'm going to put some originality into this thread by saying that the absolute scariest, most frightening, sometimes nearly heart attack inducing moments I've ever lived through in a game belongs to the first two Thief games. It's not horror, it's Splinter Cell without the suck and with older graphics, set in a steampunk world that is also full of paranormal shit.

Just make it to the Bonehoard level and the atmosphere will crush you good. Or the Haunted Cathedral with its ghosts (creepiest ghosts in a game ever... I tried to blackjack one just for kicks, and it carried on like nothing happened; not sure how, but it was creepier than it sounds). Bumping into one of those after some sneaking around hiding from something else will make you let out a girly scream.

Silent Hill 2, Resident Evil 4, and Amnesia.

Amnesia: The Dark Descent, two first Penumbra games, Condemned: Criminal Origins, The Suffering, Silent Hill 2 & 3.

Penumbra games, think that they are more scarier than Amnesia: The Dark Descent.

I am surprised no one has said Secret of the Magic Crystals.

F.E.A.R. 1. That atmosphere!
