Creepiest Non-Horror Games (Possible Spoilers)

[Mount]

Condemned: Bloodshot

I thought the two scariest bits were with the doll factory boss (and a very gruesome way of killing it) and the bear. Ohhhhh that bear. I thought it was gonna come back after I blew it up. I was expecting it for the rest of the GAME.

RIGHT?! And frankly I thought it was even more unnerving just for the sheer WTF-ness of it..

Silent hill origins onwards!
Oh wait...

Echoing others, definitely Fallout 3 and Fallout: New Vegas. Respectively, Vault 106 (the hallucination Vault) and the Dunwich Building from 3, and Vaults 22 and 34 from New Vegas, as well as Dead Money.

I have a fear of deep water and the creepy things it entails, so anytime I had to go underwater in Oblivion or Fallout 3 freaked me right out. I always play in first person, but I kept having to switch to third person so I'd stop eek-ing like a little girl every time I thought I saw something in the corner of the screen. Don't even get me started on Slaughterfish.
