I completely agree about the "monster closets" being dated. Every single rooms goes like this in D3: door opens in front of you, noisy monster comes out, spin around because secretly they opened a second door behind you. That trick only works if you use it once.
Also, I would like to see more situations where you think to yourself, "oh shit, time to run!"
It is a prevalent technique in Doom 3, but it's not everywhere. Usually it's the zombies that are just hanging out in the dark somewhere, or the occasional imp in a closet. However, pinkies break through doors and walls, imps crawls out of ducts and channels, the spiders crawl through the ventilation (which really sucks when you're in there too and hear the tickitickiticki sounds. The big soldier guys also come and find you sometimes too. I agree that it's a dated technique, but you still need some behind the door startles sometimes I think. Maybe less of them, so you don't get used to it, but D3 isn't as bad here as people say.
Of course F.E.A.R. did a pretty good job of scaring you by putting Alma in some odd places other than closets. She was always doing weird things too like when she kinda break dances across the floor at you and such. (for lack of better term)
