It seems super silly now, but when I was pretty little, we had this early Lucasarts game called Rescue on Fractalus, kind of an amazing technical achievement on a platform that was outclassed even by the NES. You played a rescue pilot viewing out of your cockpit, dropping out of a mothership in orbit, and rescuing downed allied pilots on a hostile planet, while dodging enemy fire, managing shields, etc.
When you got to a downed pilot, you'd have to shut the engines off, wait for the pilot to run over to you, you'd hear them climbing the ladder, and you had to disable the shields or you'd fry him. Anyway, there was absolutely no hint previously that some of them were no longer human. So, kid me, sitting in front of a fuzzy CRT TV, playing this thing with my brother, when all of a sudden the damned "pilot" jumps onto the windshield with a jumpscare and starts beating the cockpit window in. I probably would have crapped myself if I had to go to the bathroom lol.
Nowdays it's entirely tame, but back in the day with the right ambience, youth, and there was just something creepier about games on old fuzzy TVs.
