Don't get me wrong-- Amnesia scared the crap out of me on the first playthrough. The whole time. But as I play more of it, the effect wears off. The music, while excellent, only intensifies when there is an enemy spawned, and the same is partly true with the insanity effects. This makes the game feel predictable after a while. So I have devised a two-step plan to nearly triple the game's horror value: Mute your speakers and disable all the insanity effects. Suddenly, you have no idea if there is a monster behind the next corner, just like if you were actually alone in a dark, foreboding castle. Don't believe me? Try it yourself-- do this and play Storage, Prison, Sewers, etc. The Choir is especially terrifying due to the nature of the encounters. Soon you'll realise that what you once thought was one of the scariest parts of the game(music and sound) is actually the one crutch that keeps you from succumbing to insanity.
