Horror games

I'm a very big horror fan in general, but for some reason there are very few horror games that manage to keep my attention long enough for me to finish them.

The first Resident Evil was the first 'real' horror game I played, and on that merit alone it scared the crap out of me. Sure, it's cheesy as hell now, but man... I just didn't expect all that in a freaking game.
I had played some other stuff before, like the Alone in the Dark games for example (which were kinda scary in their own way), but Resident Evil made a big impact on me.

After that, there have only been one series of games that has managed to keep my attention and that is the Silent Hill series (which I'm a very big fan of). It's hard to point down exactly what attracts me, but a big part of it is the beautiful (and horrible of course) design, the amazing soundtracks and the intriguing storylines.
Silent Hill 2 is my personal favourite, it's just one of those games that feel more like an experience for me.
In my personal history with video-games, it is a huge chapter in itself.

Silent Hill 1 and 3 are the most immediately scary I think. Silent Hill 1 has aged very badly though, but the first time I played it... Wow. Easily the game that has scared me the most. By the end of the infamous opening sequence, I was actually panicking, and not many games can get that out of me.
Silent Hill 4 is the worst of the series I would say, but I still found it to be very worthwhile to play through. The gameplay gets tedious as hell after a while, but I really enjoyed the story.

There are other horror games (and I'm mainly talking about survival horror now) that I've tried to get into. Fatal Frame is one of the most popular, and they are indeed scary, however, they just can't keep my attention. I don't know why, they just don't hit home for me.

Rule of Rose look very intriguing. I don't know if that will ever be released here in Europe, but if it does I'm definetely gonna get it.
Haunting Ground is another game that looks interesting, but I just haven't gotten around to play it. Might buy it if I see it in a store or something.

Jam it back in, in the dark.
