Scariest game you have ever played?

So what's the scariest game ever? Has a game even scared you once in the slightest? or does any old game scare you at least once?
 
The only game that ever actually scared me in the slightest was Dead Space, but Silent Hill 2 had its moments too, so I'd rate those 2 as the scariest games ever, although I still wish some game could really make me pee my pants.
 

Doom 3, Silent Hill 3 and for some reason Alice for the PC
 
all scary in their own ways

Resident Evil REmake 
 
I don't even know if it's the environment that does it, it's the lack of ammo, the sub-par controls, the camera not showing you whether there's a zombie around the corner, and things like that. 
 
Your always on the edge of your seat.

Silent Hill 3 
mostly because I pulled an all nighter with the lights off

Condemned 2,  it was really immersive. Its pretty scary beating crack heads with a toilet seat.

Resident Evil 2, but I never played 3 (heard it's way scarier). And System Shock 2.
 
To be fair though I haven't played many horror games, like the Silent Hills and Fatal Frames. I couldn't get into Dead Space either because the control felt super stiff to me while playing the PC version, which is weird because I usually like mouse and keyboard controls.

Agh, you tricked me.  You aren't the lovable CitizenKane.

System Shock 2 and the Suffering. 

"Fatal Frame 2 hands down. It's pretty hard to find these days, but if you're lucky enough to find a copy play it. It will scare the shit out of you. "

As sad as this is, the only game that has ever really scared me in the least was F.E.A.R 2. Some of the environments just felt like something I've seen in real life (the school/hospital) and it gave me a real feeling of loneliness, because of getting so close to your friends, only to have something happen that means you're alone again. Other than that, Silent Hill 2 had some moments, but those are really the only two games that have ever scared me, and even then maybe scared is a bad word. I'd go with made me tense up.

People have already mentioned some of my first choices, so I'll go with a different one that also spooked me;
 
Aliens vs. Predator for the PC was a shooter where you could choose to play as any of the three factions.  The Colonial Marines part was especially scary since, much like in the films, the tick of the motion detector let you know something was coming at you, but you had no precise idea from which direction.  It was a "bump in the darkness" thing.

The scariest? The original Alone in the Dark for the PC. Dear god.

Phantasmagoria 2. And I wasn't even playing.
I remember watching my brother playing this and some scenes from this game were just fucking over the top in terms of gore.

I remember when playing the original doom as a little kid I would literally run out of the room when anything scary happened. And to me, opening doors was scary.

Silent Hill 2 springs the quickest to mind. Resident Evil 1 was scary at the time especially the dual shock version.
 
Eternal Darkness got me good a couple times as well. Some of those hallucinations were messed up.
 
Alien Vs Predator was almost unplayable for me as a marine cause it freaked me out so much. It was much better to be an alien than a puny human. 

When I was young, the first Resident Evil used to scare the fuck out of me.  Nowadays, I don't get scared anymore.

Condemned was pretty scary for me. I think I was 15 when that came out. I remember letting out this really weird yell when that creepy dude pushes you down the escalator and my mom thought I had been electrocuted! But there's a bunch of games I've played that gave me "stress scares," like Resident Evil 4 and Call of Cthulhu. I would actually feel helpless playing those games because of the bleak situations they put you in.

Siren: Blood Curse -- you can get inside the heads of the undead and watch them come and hunt you down.
 
Frightening.

Fatal Frame
 
I love horror games and have played probably the majority of the ones out there.  For some reason though Fatal Frame was the first one to ever truly get under my skin to the point where I was still scared once I turned the game off.
 
Also when I was much younger The 7th Guest was something that also gave me the creeps, but I still had a ton of fun with that game.
 
But hands down Fatal Frame with probably Fatal Frame 2 in second.  I was prepared for what to expect when the second one came out.

The Resident Evil remake on Gamecube. If it wasn't for Jill's grenade launcher ammo glitch, I never would have finished the game. So much about the game was terrifying. First of all, the controls aren't too hot, which I still think is done deliberately in the RE games. When you kind of have to fumble through the controls, it can certainly make situations way more scary. Then it had the fixed camera angles, which made it difficult to aim and kept you from being able to see what could be lurking just a few feet away from you. There's also a major lack of ammo, so you can't shoot too wrecklessly (unless you cheat like I did, ha), and limited ink ribbons for saving. As much as I hate not being able to save as much as I want, it really works well here and builds a nice level of tension and fear. Then you have the Crimson Heads, which were a pretty brilliant idea. When you killed a zombie, it's dead corpse would remain on the ground throughout the game. At some point, each zombie would raise from the dead and become way more deadly and quick than it ever was. You got crazy, scary bosses. All kinds of frightening enemies. Sound and music that will have you on the edge of your seat. The graphics were no doubt some of the best I had ever seen at the time. Then you have Lisa, the daughter of the owner of the mansion who had been infected with several of these zombie viruses, making her invincible. Throughout the game, you'll have quite a few encounters with her. Easily the scariest character/creature I have ever seen in a video game. Man, I'm glad I don't ever have to play this game again, but it sure was incredible. Despite all the fear it brought to me, it was worth it. Excellent game.

Silent Hill and Fatal Frame series 

Let me put it this way. I bought REmake around 2006 and I have not yet dared to play it for any long period of time :P. That's the only game I can think of that I find scary, but then again I haven't played too many horror games.

Jurassic Park for the SNES.

Silent Hill 2 and more recently, Dead Space and Silent Hill: Homecoming....I was able to force myself to beat homecoming by pushing through the scary parts, but Dead Space scared me waaay too much to progress beyond 45 mins of playing.

Easily Silent Hill 2. There were portions of that game that freaked me out so much that I ran into an area, grabbed what I needed, and ran out never to re-enter that room again. That game was nuts!

Dead Space or Condemned 

Fatal Frame II(well, it's called Project Zero II here in Europe). The first one wasn't so much scary as it was creepy, and I didn't have any major problems playing through it. But dude, the second one... it scared me to the point where I wanted to turn it off, but couldn't, because I didn't dare leave the couch. 
 
I managed to get through most of it, but after reaching the least scary place in the game(a cave under an old tree, illuminated by candles... that should give you an idea of what the game's scariest places are like), I refused to leave. The game wanted me to go back into the dark, scary-as-fuck village, but I said "Fuck you, Project Zero II. There is no way in hell I'm fucking leaving this cave." and stopped playing. Never went back, probably never will. 
 
EDIT: Oh, and all you guys who say Dead Space are pussies. That is the least scary horror game I've ever played.

RE2...Survival horror games today aren't scary because they are too action oriented, no tension.

" Eternal Darkness: Sanity's Requiem  "

Eternal Darkness. The hallucinations were freaky, but the concept freaked me out way more. *slight spoiler follows*

I've always described it to my friends as this: If you're the kind of person who needs something to surprise you, then you're not going to be scared. If you're the kind of person who thinks the idea of something starting one of the greatest conflicts in human history (World War I) in order to generate more corpses to feed to a dark god is scary, then you'll be terrified of this game.
