Image says it all. Bethesda's being overhauled and Starfield is not on its list of focus/priority.
Quake got warped into the first arena battle franchise, completely losing sight of its origins.
Quake had both a single-player game and a multiplayer deathmatch. And it came out very early in the genre showing up and was very influential in the creation of multiplayer deathmatch games. I'm not sure that it's reasonable to say that it lost sight of its origins so much as that it focused on one part of those origins.
