About no replay value...

But what is disappointing is how it's not so much scary any more on the second run through..

This is true of horror in general, regardless of medium. The "what the hell is going on?" factor is removed upon subsequent run through.

True, it's a shame, I wish I could drink a targeted Amnesia potion to make me forget games I've played, so that I may experience them again!
