It's not actually it's a more realistic world environment after getting nuked and no messiah figure appeared to unite the people.
the NCR bums on the other hand get a literal Chosen one to solve all their problems and conveniently ignore their own lore about the severity of the radiation and also somehow get a population of 700k
Like what the fuck do you expect people to build houses from in the Capital, trees like this?
Is your issue is that the East Coast which would have gotten nuked harder didn't have enough fucking trees? It's shitty world building because there isn't enough trees in the setting? When Bethesda is only realistically applying the lore from the previous installments which indicated FO Bomb's were extremely dirty
So which is it? What is the EXACT problem? Because so far it's just a lot of wah wah bitching devoid of substance.
No wooden houses because no trees
No trees because they got nuked
No trees regrew back in any substantial numbers because of the radiation PER THE PREVIOUS LORE
Substantial Radiation = Less Food = Less Water = More People Dying = Malnutrition = Having Less Kids
Mutants, Raiders, Slavers, Monstrosities add an extra level of difficulty and they didn't have Fallout Jesus in the East Coast
Why isn't it shitty writing when Fallout 2 pulls out a stereotypical Chosen one to solve problems but it's shitty writing for Bethesda to write a story where the East Coast chosen one arrived late?
