randomuser.833: I can't understand how they are able to create such shitty games they do now, with that manpower and that amount of money thrown at them.
Memecchi: Nepotism and pitching the wrong ideas, everyone and their mom knew that having "over 1,000 planets" in Starfield could only lead to barren, uninteresting maps, or that Fallout without NPC isn't Fallout... but you can't tell that to the high ups :D
I would say things went south the moment they got rid of actual writers for their stuff but introduced the dev who is a writer too, so every dev writes the story and chars for his own quests to his own liking.
So, there is no head writer who is holding everything together.
Granted, today there are a hell of writers on the marked who are just shit, even more for games, because streaming services vacuuming up the guys who would have been just good enough for games in the past.
But a good (team) of writers can do a lot of things to games.
And missing them leads to some kind of not interconnected narative clusterfuck the Bethesda games are now for decades.
