So I recently played this little game that's been circling around the web lately called Slender. Slender is a little survival horror game that drops you in pitch black woods with nothing but a flashlight and your wits ( which will soon be lost when you get a nice little surprise from our unfriendly neighborhood Slenderman.) The reason why I am posting this is because how it screws with your mind in a realistic survival fashion.
Your objective is in a very tight nit area where its hard to run away for instance. How the darkness plays into your confusion when you panic and run off into the dark woods is also a nice touch on the charm that this little piece of terror has.
If you want to test yourself in how brave/witty you are, give this game a try. I would be a good bit like being in a real time situation beings that I near pissed myself a few times playing this game.
