Looking for some game recommendations

So hey everyone. Lately I've been kinda bored lately, since I ran out of "Penumbra" in fact.
And I'm hoping you guys can help me out here. I'm very into imersive storylines and horror. Things like:

• Call of Cthulhu
• Penumbra
• Amnesia: The dark descent

Is kinda my thing at the moment, so I'm wondering, does anyone have some recommendations for me?

Have you tried Nightmare house 2? It's a Half-Life 2: EP2 mod and I have to admit that it made me jump a few times.

Also,

But RE5 doesn't deserve #1, because it's not scary and just plain cheesy.

Thanks Dev, might look into some of those

My first ever RPG, still play it and love it!
Awesome Soundtrack and SFX. Graphics are average but quite a good grabbing storyline. Gothic 1. Number 2 onwards pretty much fucks up the whole series!
