Yeah, an overarching story seems to be way more important in more modern games than it is in Doom.
I’m only realising this now, but I suppose the type of game that Doom is developed into more multiplayer-focused games (Quake, Unreal Tournament, Counterstrike, Overwatch). These games have more in common with Doom I feel than titles with a big single player campaign such as Half-Life or Bioshock or Far Cry.
I think Doom was somewhat popular to play over LAN at the time, but I’m not sure how feasible online multiplayer was back in 1993. Does Doom even support multiplayer over modem or something?
