and Doom are nice in their own way, but the really impressive work is found in games like Silent Hill or parts of Thief, where the game is more about self-preservation than bringing murder to all of the creeps. Monster shooting galleries like Dead Space, Resident Evil, F.E.A.R.
I’ve said before that I think that survival horror (real survival horror, the kind intended to invoke actual fear) is some of the most challenging work a game designer can undertake.
