The first time a video game actually scared you.

Clive Barker's Undying. Criminally underrated game, the first half of the game that takes place in the mansion and then the monastery had me scared out of my wits. It was released back in 2001, published by EA who didn't know what a masterpiece they had on their hands so they didn't promote it almost at all. You can find it today on GOG. The graphics may be a bit dated true, but if you haven't played it, do yourself a favor and play this game.

DOOM 3!

I got it on my 13th birthday and played it at night, stopped, then my brother kept playing it while I was trying to sleep. Nightmares ensued. LOL
Also, Dead Space was terrifying

I don't remember exactly, but I think the first game that scared me was Silent Hill. It's not the scariest game I have ever played (Fatal Frame 2 gets that trophy), but it freaked me out, and had me looking over my shoulder for a while. It's maybe not the first time I have been scared in a game, but it's the first one I can remember.

For me it was playing PT on vr after a couple O' tabs of acid.

First time a game scared me was resident evil 2 on N64. I was 11 maybe and it was my first time playing a horror game.
The next game i played that was scary was silent hill 2 due to its chilling atmosphere and psycological mind-fucks (which in my opinion is the best way to actually instill fear). Then the 3rd game to actual send a few chills was the first hour of playing doom 3. Say what you will about the gameplay or the change of pace of other dooms, the first time you load that on your pc, put headphones on, turn off the lights, that game is freaky. Of course after playing for more than a couple hours you can become numb to the fear factor.
*sigh* these games take me back to when i could get scared. To many saw movies and B-rated psycological horror movies on netflix made me numb to any gore-cringe-horror or creapy horror.
Lets not forget the ultimate horror as an adult, when your wife turns into Beelzebub because it's "that time of the month" and you forgot to buy her chocolate....in the words of iron maiden "run to the hills"

In terms of actually being scared I'd say Half-Life 2, I lost count of how many times a Headcrab would make me panic.

Though in terms of being unnerved/put on edge, it might sound a little weird, but Shadow Of The Collosus made me feel really uneasy. The world was so empty that it just felt like eerie. Also the weird ghost things when you returned to the shrine made it all the more weird and cold.

I remember going over to my friends house when he had just gotten Resident Evil 4. I remember watching him play and the first village area when you fight the first chainsaw guy was enough to spook me from playing it for over a year. Nerves were wracked. lols

Games that put my character in peril at great heights put butterflys in my stomach just as much as actually going aloft did.

But unless jump scares count no game has scared me.

The first silent hill on playstation when the knife wielding babies stab you to death in the start of the game the camera angles and the music. First game I had to turn the lights on and stop playing lol.

At his time I was so scared on Doom 3, that I tough it to be the scariest game ever made. I suffered all of it, but I felt "this is art", and was so addicted.

It was only overthrown by Alien Isolation, pretending to play "Impossible mode".

I also enjoyed impossible mode in Dead space 1 and 2, so much that I always try to play games without saving.

The inminent feeling of failure, of making one mistake that kills me, is so scaring and exhilarating... I tried to play Dark Souls that way, but always failed miserably...

When I was around the age of 5 or 6 my Uncle tried to get me to play half life 2 when it first released.

While not nearly as scary playing now (if at all) the valve logo screen with that eerie music was enough to set in that feeling of terror.

And don't even get me started when he had me try out doom 3

[manesni]

I don't remember if it was the first game that scared me but the one that still stands out today was the butcher in diablo 1. FRESH MEAT!

The intro for the game creeped me the hell out too.

Probably Metroid when I was about 5. Not any particular jump scares but an overall sense of dread at an age when your imagination is at it's peak. Also around the same time, I know that Haunted House for Atari 2600 fucked me up.

Half Life Opposing Force, I was 6 at the time.
When the headcrab jumped at me, I got so scared that I jumped out of the chair and threw the mouse into the wall, I only finished the game 10 years later.
