A computer game that can actually scare you?

Amnesia: The Dark Descent” seems to be such a game:
How many games have you played that were so spooky you actually had to stop playing them at one point to catch a breather? Usually when the game tells you “hey, you have to go back to the scary area™” you go “bring it on – I know where the monsters are now, so I’m no longer afraid”. When Amnesia told me I had to go back to the Choir area I said fuck that shit, and went to browse reddit for a bit, because I was totally not ready to re-experience it after the first time.

Great idea: it’s a monster game, but you are just Joe Normal running away from them – no heavy guns or magic shields. That means you will relate to your game persona, which seems to make the game scary.
