Traumatizing Videogame experience?

Reboot for Playstation. This game was one BIG traumatizing experience, the controls are terrible, the graphics were bad and age even worse, the gamepla-- Okay, it wasn't so much traumatizing as incredibly suckitudinous.

But being serious now, I think once I was a very creeped out by the Redead enemies in Ocarina of Time. I'm not the only one to have the found them scary I see. However, the noise they made was fear summoning, and the fact that they grappled onto you if you got close to them made me tremble. I think that was one of the few times I was actually scared by a video game, but I'm not even sure that I find them mildly frightening anymore. Since then I've managed to play much scarier games without flinching.

Jam it back in, in the dark.
