Assuming it's a surprise, this is Earth All Along. Genre Shift is similar, but that's more about tone than plot

I have no idea the answer to your question, but I now know like 99% of people on lemmy have shitty reading comprehension.

Genre Shift

Aladdin (1992). The Genie is the last survivor of the AI wars and has mental damage. The Cave of Wonders is another remnant. “Magic” is low level AI responding to human intent. Iago is an uplift. Agrabah is literally a generic Middle Eastern country because it was assembled from the fragmented records of what remained of the Middle East.

The Adventures of Brisco County, Jr. is my personal favourite of Bruce Campbell's work. Starts off as any ordinary western, before getting very, very weird.

Come to think of it, Firefly might count, after watching Serenity at the end of the series.

Yeah, Adventure Time

Not 100% sure, but these come to mind.

• Science Fantasy
• Dying Earth
• Post-Apocalyptic Fantasy

You mean like Adventure Time?

Star Wars is fantasy, not sci-fi. (Technically it’s a space opera, it not at all about science or how that science might impact society.)

Just because there’s technology, or it’s post apocalyptic doesn’t make it not fantasy.

Shanara chronicles, too.

That wouldn’t fall under a single trope, but would be a combination of several tropes. After The End would be a requirement, and for technology that is like magic to those who live in the world would be Lost Technology.

You mean like “dwarves and elves are GMO humans” and “magic is actually tech gadgets” ?

To clarify, are you asking if there's a specific genre to Planet of the Apes where there's a big reveal that this is actually just earth after some society ending disaster? (And similar stuff but that's the first that came to mind).

NK Jemison's Broken Earth trilogy comes to mind, fantastic series it that's your thing

Post Apocalyptic Fantasy and Post Apocalyptical High Fantasy are two phrases I keep seeing.

I don't think there's a trope name for it, since the trope itself would spoil the story since this is often a twist.

Hifantapodysfut.

Pronounced [haiːfæntʌpoʊdɪsfuːt].

(Transcribed according to IPA/English.)

Star Trek comes to mind unless you disallow scifi (as high fantasy usually would iirc, though notably "space operas" really do seem to blur the line).

LOTR could be argued as such - there was an earlier age of beings from which only remnants survived, and then we also watch live as a second epochal transition takes place, where the likes of elves disappear. I mean, either way it's not "our reality" type of age - but then again you couldn't ask for that from "high fantasy" by definition :-).

And it's a very common trope in video games - e.g. Chrono Trigger that is arguably the best RPG of all time (shitty graphics, even for its time, but hands-down the best story I've ever seen, made btw by the creators of Final Fantasy who were given the freedom to do whatever they wanted for it). Edit: another one like that is Lufia - not a ground-breaking game but highly regarded for doing what it did so very well, at its time mind you.

And I've seen some others where like basically Earth is implied to have been destroyed (or at least it is unclear whether it survived a world-ending event), but the singular human remaining lives on, in space, but in something like a series of interconnected "worlds", some having higher levels of technology than Earth ever managed to reach while others are set in earlier timeframes. And dealing with noncorporeal beings from like higher dimensions, and entities like a god inside the machine - so definitely once again mixing up heavy elements of "high fantasy" (with the likes of swords and magic) and sci-fi.

If you can dream it, someone has likely written it. Books are freaking awesome! 😎 So too are other mediums, when profits are not the exclusive focus.

Where have you seen this? I've been looking for some stories like it
