i'm saying it's too slow, 120 years is a long time in terms of cultural changes. also, i pointed out how they made a jump from the 50s to the 70s/ 80s with some things and not others, which makes little sense.
Which is what makes it a diverged timeline.
I happen to agree with you that music would have evolved, but I am inclined to let fallout devolopers continue what they see fit for their theme. it is things like that which make it a unique IP and not just another post apoc game- they must differentiate themselves somehow.
You cant look at it as a "the 50's stayed the 50's forever" scenario.. It is more of a :"the future was how those in the 50's imagined it would be"
scenario. a person in a past tense alternate realty's dream of the future.
