The answer is Bethesda. This is how we ended up with Fallout franchise being completely different from Fallout 1 in depth, writing quality, atmosphere, internal world integrity.
Fallout 1 was hard sci-fi which took itself seriously. Fallout 2 took some mis-steps but it was still a world.
Fallout 3 was a full-on clown show with a self-contradicting world, retarded writing, the game changed from "you're a nobody in a Wasteland" to "you're the Chosen One and the world's your theme park" from the start. Fallout 4 was a full-on clown show with even dumber dialogue choices. Amazon TV series is beyond a clown show, it's a bottomless pit of decline in narrative storytelling - even if we ignore all the lore violations.
It's not hard to trace what started this. It was always Bethesda.
