I think that a lot of Bethesda's narrative problems is that they come across as an "excessively permissive GM." You know, the kind that will let their players do whatever they want, a la "you guys want to just walk into Mordor at level 1? Cool."
Having a permissive GM is the holy grail of RPGs, and Fallout 1/2 came closer than other games did.
Fallout 3 just allows you to walk places. It only has a permissive GM in the same vein as Far Cry 4 or GTA 5 have a permissive GM, which is to say, it doesn't.
A permissive GM is a combination of several levels of world reactivity to who you are, NPC reactivity to what you do, multiple quest solutions, choices&consequences, ability to skip content or address things out of order, without breaking the game. Fallout 3 is a rigid straitjacket of a game. Hence the term "walking simulator".
