I never had a chance to play Fallout prior to Fallout 3 but have a pretty firm grasp on the story but I've always wondered is it simply a design choice that even though the bombs went off int he future (2077) the era looks very similar to the 1950's. Everything from the music to the architecture, cars music, tv, the technology might be advanced but it is all reminiscent of the 50's. Is it simply a deign choice or is their an in universe explanation?
