Fallout has the exact same “feel” as the game franchise. The art, costuming, and music nails it.
My question is: what is the overall genre of Fallout? Americana?
Google search always comes back with MMO/FPS but that’s not my question. What is the genre imparted overall?
For instance, BioShock was 100% Art Deco. So, what is Fallout?
It’s definitely a mixture of certain aspects, at times it feels like Art Deco, but feels like it definitely a retro futuristic aesthetic in its pre-war setting
Atompunk is the term you’re probably looking for.
“Jet Age” of the late 50’s is the style term you’re looking for. Hyper modern, smooth lines, hard surfaces. This lines up with the music as well. Here are a few examples. Is this what you’re looking for? 
yah. that looks like timeline 6. The worlds fair never ended. just expanded and took over every city.
Oh, I think thats timeline 6. Timeline 6 humans survived rads better we are in 42 I believe. hehe. too many cant be sure. 42 is funniest one by far tho I think,
Early cold-war Americana.
The first scene pretty much sums it up. Children's birthday party in a large mid-century style home in the Hollywood hills overlooking L.A.
Everyone on edge with a permeating existential dread over nuclear war.
Cold-war Americana.
I think that fits.
The pre nuclear blast aesthetic would also fit in the "atom punk" niche.
Never heard of that one before.
Not sure if it's just algorithms doing it, but I've been seeing more chatter on the different types of punk aesthetics.
(Probably due to the relative success of the cyberpunk revival)
Steam
Diesel
Cyber
Atom
Solar
On and on ad nauseum.
There's pretty much something for everyone.
The technology is effectively just a fun sci Fi twist on what could have been if the tech in the books of the 50's had come to be produced.
The earlier 2 PC games were full of more nods to pre digital technology.
The series is more rooted in the more modern game aesthetic.
I binged the whole season in a day. Love the show.
It's got some retrofuturism in it (in the year 21xx, we'll have infinite energy and everything still runs on CRTs and cassettes)
