Best Horror Game

LSD Simulator

Fatal Frame Series. Amazing and psychologically scary.

Obscure and its sequel. You would want to play them. (:

I'd go with Project Zero/Fatal Frame 1 & 2 for PS2 or Xbox.

don't shit your pants, it's a survival horror

I'd say Amnesia, Penumbra and Cryostasis :D

You should probably check out a game called DreadOut. It's still in development, but it's pretty good! :)

Condemned: Criminal Origins

saw

Lone Survivor

Alien Colonial Marines. Damn, that's scary.

surprised noone said this. Sanitarium?

Amnesia: The Dark Descent / Silent Hill / FEAR 1 / Resident Evil 1,2&3 / Dead Space 1 & 2 is good too..

The scariest for me is the Fatal Frame series

A positive pregnancy test

Condemned is a pretty scary game, it's got a weird but nice story also!

silent hill 2.

Why nobody havent said "Nosferatu: The Wrath of Malachi".. I dont know if its scary now but when i played it first time it was frigging scary.

Darkwood.

Still in pre-alpha and greenlight, but looks awesome.

minecraft, and counter strike and lego star wars are some of the scariest games to date

The suffering?

Resident Evil 1,2, 3 and Code Veronica :P
Alone in the Dark 4

Fatal Frame saga, F.E.A.R., Amnesia, Condemned.

Paranormal, Condemned and Call of Cthulhu Dark Corners of the Earth.
