I am not sure why people keep dismissing the scariness of Doom 3 due to the "surprise" nature. We are talking video games here people, not movies. In movies like Saw or Seven, you can be afraid from a psychological standpoint (ie F.E.A.R.) because you have two hours to really get a feel for the villain/monster. You don't have that luxury in games. In video games, voices behind you, screams, and *surprises* are what scare you. I agree, the little girl in F.E.A.R. gets my heart pumping sometimes, but when you are in the dark 80% of the time and there are monsters that come out from behind you, in a room you ALREADY CLEARED (Doom), THAT'S scary. It's also very lame of iD to design a game that way. They basically "cheat"
