I love horror games! The problem is that I'm no longer scared by them, in fact I usually enjoy the whole "scary" atmosphere. After the first time playing, the game is no longer scary and then turns into a quest for getting all of the extras, weapons, items, alternate clothes, different endings... I can only play a scary game so many times before I know where all of the enemies and things popping out at the screen are.
Anyway! The last time a game scared me was just a few days ago, I had been playing for hours without saving and my character was almost about to die.
