Done with Overture. I played it all day long, and experienced one really, really shocking moment (I was scared all the way through, but this stands on top of all). After getting out of Shaft 13 (or was it 12, I'm not sure), I knew there was a dog around, but didn't see it. Just as I was turning, it ran in my face and hit / killed me. I jumped off the chair, and shivers crawled all over my body. I quit the game after this, laid down for a hour or two, and continued the game after I woke up.
One of the most realistic feelings I've ever experienced.
