I played this game like 2 days ago. I even got scared because of the intro and stopped playing. Seriously, its scary, and the worse is that it has jumps + that moment when you feel that the monster is right behind you + scary sounds = scary
Amnesia is cool too. Doom is not creepy, just shooter. Singularity has stupid story. Alone in the dark could be scary but controls are retarded = not scary but pisses off. Speaking about some scary games I do play Far Cry 1
