For people out there, I prefer Blood most than all because of the graphics, the creative weapons(who would ever imagine to use a lighter and a spray or a flare pistol?), and the storyline, also the bad guys. Doom is good but not that good but is better than wolfenstein and is logic because Wolfenstein 3D was released before and was of the same creators. and i can't say anything about duke nukem 3D because it crashes in my computer, I liked the PSOne Duke called Time to kill but that isn't FPS.
