Question Of The Week: What Scares You?

Look, I remembered to do Question of the Week this week!

The horrific Phantasmagoria 2 became available on GoodOldGames.com this week. I haven’t played it since I was young (and it’s not appropriate for young people, bless my parents) — but I remember that it scared me worse than nearly any other video game ever to date. I could not even finish it for a good couple years because I was too scared to try things and die over and over. It took me a few years before I was brave enough to print out a walkthrough for the very last section and beat the game.
I have a sneaking suspicion that if I tried it again today, it would be terribly disappointing, possibly even hilariously terrible. But paradoxically — kid you not — I’m still too frightened to revisit it.
What game scared you worse than any other in your memory? Do you feel stupid about it now, or does it still scare you?
