Dungeon Master, circa 1987. First example of stereo sound in a video game, early in the game I could hear something shuffling around somewhere in the dungeon. I moved forward & turned 90 degrees left and was presented a ghoul who, right at that exact same instant triggered the animation to lunge and give a moan. Trouser change.
Undying. Saw some shotgun shells on a table by a wall mirror, just as I approached it I saw a spooky floating guy appear behind my reflection reaching for me, I spun around just in time to see him disappear.
Black & White. During a late night session I hear the game whisper my name. Literally whisper my name.
