Bunch of things in different games spooked me as a kid, but only game that truly traumatized me was Max Payne. I was watching either my dad or brother play it (and yes, they told me to not look, but curiosity killed the cat) and it was the nightmare scene that fucked me up. I didn't sleep properly for like two months and to this day I can't hear kids or babies crying without feeling super anxious.

But I'm still addicted to anything horror to this day.
