Ever got the crap scared out of you by an Amiga game? So much that you were afraid of picking it up again? If you can't remember scary moments from Amiga games, feel free to include games from other platforms.
I had two almost piss-pant moments.
In Uninvited, when the first person you encountered in the mansion turned around revealing its hideous face ... and then proceeded to rip the innards out of you. That moment had such an impact on me that I never dared playing the game again, even though the atmosphere was pretty darn epic.
Then, there's Space Hulk. I'm not sure why, but every time those Genestealers came out of nowhere (and everywhere) to tear my team apart, I wanted to turn the game off.
Silent Hill on the PSX was pretty sick too. The naked, knife-wielding babies made me nauseous. Funny, I had no trouble battering the minions in SH2 to bloody paste, but the babies ... god, those bloody babies.
