Sorry for the double post, but as @cocomo said, Forbidden Siren. That'll screw you over. And oh, FEAR series too. Side note : When I was a kid I was afraid to play Half-Life 1 due to the head crabs. Back then the graphics were top notch. And it still scares me. Fatal Frame hit in the ps2 era... All you have is a camera. So.. You do the math on how scary that is.
Hmm. For a good jump, Paranormal Activity. To hide behind the boyfriend, Saw. And for thinking, The Uninvited.
I forgot silent hill there is this game i cant remember the name of it ill resesrch it in the morning but it is supposed to b scariest game invented its only a pc game tho
@Rose: you dragged people into movies But really guys, movies are too many to name Oh and I remembered. Dead Space series are freaking dark and scary clock tower is good too. But I got bored of it Horror games are hard to find now... Example, resident evil series... From horror to action.. Oh well.
Guys! Hotel 666! It's a pc game! Well, you can just google it, and find it. It's scary! Specially if it's at night. And you're alone. With the volume up.
Slender was funny as hell I would have to say The Grudge was the scariest shit I ever watched and played.
Wasteland Fall Out 1 Silent Hill 1 Are Games that scared me when I was younger, and are likely to be the reason why I do not get frightened easy any more (sorry if English is not good, I am tired and translate is hard)
Left 4 dead Resident evil Silent hill (never played, just like the gameplay) Slender SlenderMan (different game) Amnesia
