I am fascinated by games with 2D art that still manage to give you a good scare. I guess what I find interesting is if a game can manage to translate the scares and audio design which we know from 3D environments and movies. I have never really played any though. I would love to hear some suggestions, especially with Halloween coming soon!
I enjoyed these games, but as you said, they are not very scary, especially after you get used to the atmosphere.
