Yup. Space chainsaws. They make no sense, but at the same time they make perfect sense.
The whole "fast movement" thing didn't really come into play until Doom 2016. Doom, Doom 2, Final Doom, Doom 64, and Doom 3 aren't really that fast. id didn't move to the whole super fast movement until Quake, which Doom 2016 feels like an extension of.
Shooting things with guns in first person. While Wolfenstein did it first, Doom popularized the genre and the FPS genre began by emulating Doom.
Ha I remembering playing goldeneye and was like what is this shitI clicked on the thread thinking "no reloading" which I guess falls under the first option.
