First of all, I love being scared. Not spooks but truly being moved emotionally. The game that has achieved that the most for me is Silent Hill 2, I got into the story so much that it was the story that got into me and scared me. The game itself is not that scary actually, but when you add up the story, twisted monsters and atmosphere it's a terrifying experience. For those who have not played it, the twist in the story is the best (although not the most original, but effective in its delivery). Awsome game.
