I agree with InBlack: Doom1, Doom2, and Quake1 were pretty much the pinnacle of id. I'd rather see Quake return to its roots. The whole Strogg thing was well and good, but calling it "Quake" effectively eclipsed the feel and aesthetic that (for me) made the original Quake so engaging. Quake should, in my mind, be less about sci-fi and more about gritty techno-gothic horror, with periods of apprehension interspersed with sudden moments of frenetic, stark-raving terror.
