make fantasy great again!

Other way around. If your fantasy / sci-fi novel does not sell well, rebrand it as a new groundbreaking "history". Include how it gets ridiculed by main stream science that does maliciously ignore all the evidence.

You have instantly gained a huge, uncritical customer and fan base.

Edited a few typos.

Silly L. Ron Hubbard, trying to convince people to follow in your footsteps again?
- Battlefield earth is unironically good though
- Lol this is exactly where my mind went after reading the op as well

Uncensored.

I remember a game I played ~9 years ago where you could send ships to explore the world and when they got back you had the option to reject their findings. If you never rejected anything, the world would be exactly like Earth, but everytime you rejected it would randomize the section that had been explored and over time it would start generating a whole new world.

And you could even make the planet flat by rejecting the discovery of it being round.

That sounds interesting. Do you recall the name?
- Found it in my history, it's Neo Atlas 1469.
I want to play this
That's a super cool gameplay idea.
Oh my god that's so cool I wish I'd thought of it. It's similar to this idea I've been mulling over about a world where areas are fixed/dynamic based on how certain people are about them. But that is a better implementation than anything I sketched up.

Here's an updated map. AFAIK, the author isn't actually a flat earther, but made this to meme on all the conspiracy theories at once. And also for the love of worldbuilding.

And they also made and explanation post. It is unironically pretty good.
so Asgard and Atlantis are real after all
- Don't be ridiculous. They have a world-sized serpent, not an ice wall, which is completely illogical.

Conspiracy theorists don't have the imagination to write fantasy literature. They can't account for the inconsistencies in their theories and 99% of the time the reason they give for why a certain thing is the way it is amounts to: "the Jews did it".

JKR can't write a consistent world that makes sense either.
- Well, she is a conspiracy theorist too. Mostly directed at trans people.
Yeah I remember loving all that conspiracy, X-Files, Umberto, past lives, lost cities, etc etc — all that stuff. But scratch at any of it and it's always some of the dullest, unimaginative reactionary bullshit just a hair's width below the surface.
Not to stereotype, but reminds of prison where everyone complains about capitalism without actually using that word (probably different now), but talk to them for more than 30 minutes annnnnd yup that's antisemitism again. Fucking hell.

-reads up on new Flat Earth lore- ...did...did a Flat Earth lore creator watch Attack on Titan recently...?

Brandon Sanderson is a Mormon and is a professor at BYU. I interpret his works as Mormon fanfiction.

He's pretty good at worldbuilding, too. And so far his worlds are actual spherical planets.
This makes the end of The Wheel of Time make more sense.
- Asking is good faith, been some years since i read wot. What part of morminism made it into those last books?
  Dont get me wrong, what a lot of us see as "prudish" shows up in his writing, but ive only noticed it in his stuff, not the wot ending.
  I was too busy crying when spoiler i dont how to black out matt saved the orphan kid whos now his family while the kid is crying in hell or its equivalent and matt is the first one to ever come back...
Mormonism and BYU need to be abolished.
- Whats BYU? Also, dont get me wrong morminism like wow, how could anyone today believe it? But on the other hand, my main one, calling for the ablosihment of a religion is , uhhh, a little trumpey if you ask me.

I should call her…

It's turtles, all the way down.

Surprised nobody mentioned this earlier.

Hell yes! I totally use ley lines, contrails, and all sorts of crap in my DMing. It works crazy well and has so much documentation my job is easier.

Falling for conspiracy theories is a mental disorder. They're failing to process information critically. They couldn't write anything because writing requires skill, persistence, and consistency.

And writing, particularly editing, requires considering multiple possibilities and disregarding the bad ones.
I'd say education disorder, not mental disorder

Turned out, writing interesting compelling stories is hard actually. You need way more than an idea, especially if your idea is "what if true things, but the opposite"

That's a great way of saying this. I used to enjoy talking about this stuff and when people would question if I believed any of it I'd have to explain I just like thought experiments and writing syfy shorts.

Yeah! It's like just considering these things is fun and enriching. You might let yourself get swept away in the fantasy a bit, but ultimately you're telling yourself different stories.
So they only ever feel like stories, and not like, a whole to paradigm that you're going to flash your BIOS with rofl. Just maybe run it in a sandbox/cgroup and see if anything actually fun or inspiring comes out.
Pardon the opaque metaphors.

For that you need to come up with something coherent

There's a novella that toys with the concept of an endless, flat world https://app.thestorygraph.com/books/a6f9dcca-1b82-45dd-ba41-70b313e4c642

Fun fact. I made a fictional world that is a flat earth (flat planet?) I just found the implications of such a world to be fascinating and went with it.
