Like just
I don't even like the kinda 40s-50s pulp comic-art it draws a lot from, or 1950s car Americana, or post-apoc settings (tho it's less 'Woe, life is bad after The Collapse, now go fetch me 10x radzombie pelts'
and more "That was so long ago it's become mythology, but some of the tech is useful if you can use it"
Kinda like Caves of Qud or Book of the New Sun.. (not 2 things I ever thought I'd link to short-lived 90s environmental cartoons)
