This game beats F.E.A.R. by a longshot, infact, F.E.A.R. doesn't even compare to how much fun Quake IV is. Quake IV fixed some of the things that were wrong with DOOM III, like the human models looking like action figures, the human models look a lot better than what they did in DOOM III.
Quake IV has a better action in it than F.E.A.R. did and almost infinitly more than DOOM III. The only drawback is I cannot run Quake IV on ultra settings with everything to max at 1280x1024 (shadows off), cause the maps are just too big (I could do this in DOOM III because the rooms you were in were very small), but I can still run it on high settings with everything other than shadows on at 1280x1024 and barely hit any places where I get any slow down.
