I don't think gore is scary. Amnesia is all about the atmosphere.No offense Sera, but you watch gore movies like they're porn, so I'd have to say your scary gauge is a little on the skewed side.
Not responding to Bowielee here, I don't think that the Fatal Frame games are bad. Quite the opposite really, I think they're about the best horror games ever made this side of Amnesia which I think has dethroned them.
