Horror games as good as Amnesia?

[HateSolstice]

Amnesia and Penumbra are actually the best horror games.
So, you can't find any better game, so you should accept this.
But there are some other horror games even good and scary.

I started playing the Silent Hill series. The puzzles are even harder than Penumbra, the atmosphere is same creepie as the Frictional universe, and the story is really interesting.
But the only thing what is breaking the horror is that you have to fight your enemies.
And the gameplay (controls and camera etc.) is a bit complicated, but you will learn it very soon.

At all, I think, Silent Hill is a fantastic horror game. It is scary and has brilliant puzzles.
The atmosphere, the sounds, the effects, that all is a master-class!

With the exception of very specific events, you never HAVE to fight your enemies in Silent Hill.

As for the topic at hand, are we discussing purely horror games that make you jump out of your chair/skin? Or are we going with creep-factor and atmosphere as well? If so, I have a few extras to add.

Phantasmagoria: Yes, it's a point 'n click adventure game. Yes, it has really bad acting in it. Yes, the story is pretty terrible. However, it was still a pretty decent game overall, and there was enough creep and bizarre stuff in the game to put it on my list.

7th Guest/11th Hour: Purely puzzle-oriented, but still had a nice atmosphere to it.

F.E.A.R.: FPS with horror elements. I personally enjoy it.

Hello Kitty Online Adventures: If this doesn't give you nightmares, nothing will.
