AITD, NS, Eternal Darkness (Score 1)

The first game to ever scare the crap outa me was Alone in the Dark. I was like 8 at the time, and had dreams for months and never even finnished it. Recently Eternal Darkness for GC also did a good job with their Insanity effects also scared the crap outame sometimes. Currently I'm playing Natural Selection(HL-Mod) And its got to the point where i walk into a room and check above the door for hiding aliens (yes sad i know) But its the most enjoyable game i've ever played, simply becaues of the ammount of teamwork it requires, which causes a great atmosphere along with the gfx and sfx.
