I do agree that this is mostly because of the story they've chosen to tell. Instead of framing the character you create as just an exceptionally talented adventurer or even just a normal adventurer involved in these plot points, you are the one and only chosen warrior that can save all of existence. It means that content has to be designed in such a way that any time it intersects with the narrative you have to be the only one they are speaking to or the only one seen achieving things.
