Amnesia the Dark Decent and Slender
I expected a scary game, maybe even disturbing, but nope.
I'm not trying to be internet badass "Hurr I'm so strong and manly and brave", they just weren't really scary and didn't suck me into the storyline or make me feel like I was actually there running for my life.
Most of the YouTube videos are just people overacting to what their viewers want to see. Or they scare easy.
