Not sure why you're not scared. -.-
I can just tell you I bought it, but i'm currently waiting for a weapon mod. XD
Seriously, when you play a game, or read a fiction book, or even watch a movie, if you want to truly enjoy it you have to regulate your internal perception of reality. Being a kid helps a lot, but adults can, too. Don't be costrained by the borderline of reality.
Also, Amnesia is not a game that just scares you. Games like "F.E.A.R." do that, or movies where a monstruos image of a bleeding monster appears for a third of a second while you're walking in the park. But i wouldn't define that scary, it's just a scaring trick. Amnesia doesn't use this cheap tricks. Creatures roam around free, and if you do as i've said above, you'll feel your heart pumping when you'll have "something" hunting you in a dungeon where you're slowed down by water and he gets closer...closer...will you turn?
