I've had one uniquely personal creepy moment while playing Oblivion. In dungeons I kept hearing a sort of chinking sound that I was sure wasn't a part of the soundtrack. One day my friend was with me while I played and when it happened, I asked him whether he'd heard it and he said he didn't... I had to take a break from the game after that.
Another game that creeped me out a bit was Superbrothers: Sword and Sworcery EP. I found the game's atmosphere a bit weird from the beginning, though not in an unpleasant way, but then the Gogolithic Mass happened.
The Neverhood could be quite unsettling at times as well. Walking through an empty world with the only sounds being your footsteps and the howling of the wind. The creepiest stuff in my opinion was the Weasel warning and this:
Hm, literally falling off the world seemed way creepier when I was a child.
