Old Russian scifi: welcome to the crapsack post-apocalypse. It's strangely similar to the current day. So, the protagonists do what current day people do: grim philosophical brooding.

Current Russian scifi: Awesome Russian soldier dude gets isekai'd to World War 2 and defeats the evil Western bastards. Help the author is trapped in Putin's book factory send help

Australian Sci-Fi: The rest of the world is forced to live in a desert wasteland full of criminals the way we do every day, and they struggle to adapt.

American sci-fi: America is technologically, morally, physically, and intellectually superior. And the answer to all ills is more science.

British sci-FI: nuclear war. Almost everyone dead. Bit of a Tuesday, innit?

Hey! There are also Japanese sci-fi which just validate the author's fetishes. There's even two I know where that fetish is specifically polygamy.

Ukrainian sci-fi: Everybody just fucking dies. Nobody's fault, really. And there's meaningless but meaningful love. Also, it also functions as a very long music video for the song "Voyage Voyage", whose lyrics the author of the manuscript has clearly seen translated. (Referring here to "U Are the Universe", which I liked a lot!)

I'm a Judge Dredd fan, can confirm it's all Americas fault.

But Fallout is American, not British

Russian sci-fi: every single person in the future is white.

At one point in my life, every time I got a serious stomach flu, I would watch Threads (1984) so I could enjoy my life.

By Dawn's Early Light and The Day After are fun too.

Isn't most American SciFi the direct counterpart to British SciFi?

Space army fights bad aliens. Space radioactive now, but bad aliens dead 👍 Space Captain hero.

Also, my friend needs some examples of French SciFi.

British one sounds realistic
