What is the perfect eerieness?

[Mina Darsh]

Alright, gonna trail a little bit off the 'are corpses scary?' part and move on to creating the sense of danger. What I thought to be a really good idea to scare someone in a game, is to have sounds play like in Penumbra, but not exactly the same. I haven't played the parts myself in that game but I assume it was ambience like the dogs in the Back Hall part in Amnesia. What I wish to try sometime is to have sounds play right next or behind the player, clearly extremely close, but when you turn around... Nothing. These are the kind of scares that I like, you are being fooled into believing something dangerous or unsettling is near, but eventually you find out there isn't. And if you're really mean, make something happen at the point where the average player would think: "Bah, it was nothing..." Of course yeah, need an explanation

(Makes me wish Amnesia had true bug-free hardware surround support.)
