I don't browse specific subs, but I do google "(specific question) + reddit" sometimes. What sticks out about r/worldbuilding beyond it being on reddit?
R/worldbuilding and even r/magicbuilding are great in intention but terrible in execution. They give people the excuse to bring up all of this vague nonsense about their world and it usually results in them saying something like "how can I make a fantasy world without those disgusting European white people themes?" or "how do I make a magic system that's the cliche 4 elements without being cliche?"
The "builders" there don't write or make anything. They are just noise and remain unknown because reddit writing has been taken over by the mentality of "I'm doing this for me and for me to feel happy" which results in empty upvotes rather than an actual accomplishment.
I guess another way to put it is that people try to follow the examples provided from the hot posts and then they never intended on actually making anything or what they do want to make has zero consistency/focus.
As for actually world building without being a sperg about it, the key is emanation. Once I learned this technique, world building has been more simple than ever and my worlds tend to get praised.
The entirety of a world consists of only 4 things:
1. philosophy
2. geography
3. ecosystem
4. culture
You start with the philosophical idea(theme), you give it the setting, make the characters, and provide them with a culture that relates to the theme and something in real life.
The philosophical idea usually starts with ontology (being) which is in the form of 3 main categories:
1. Materialism(everything is of a physical world)
2. Idealism(there is a sort of dream world above the physical world)
3. Monism(physical and dream world are together and a third substance is above as a spiritual and mysterious world)
We like anthropomorphic animals in stuff like cartoons because animals are symbols and relatable, not because they are a strange creature that walks and talks. The relatability is from their humanization.
People get autistic about this when they do NOT relate to the audience. They instead do their own thing, have no real message or aesthetic, and it becomes a nonsensical mess.
One thing that fascinates me to no end is how autistic stuff like Sonic the Hedgehog is. It's an animal that's blue and wears big shoes which cause an ungodly amount of foot fetish porn.
The creators designed sonic so close to what they thought kids would like, that, lo and behold, kids liked it. Autismo kids went bonkers for it, because it's not realistic at all but it has all the symbolic things they enjoy. Sadly this is mostly fetishes, because autismos are trapped in their own toon world, and I do see it in a bit of a Freudian way where it's sexual even at a young age.
At least for how an autistic person becomes a sonic fan in the first place.
My point with that is that it's hard to avoid appealing to the autismo as a creator, but appealing to such doesn't mean the process was autistic.
The creators knew their direction, they understood the world they made, and that didn't go away until new knuckleheads came in and ruined it.
Same goes for current woke nonsense like Rings of Power. They went full sperg trying to get that show to be the propaganda it is. They didn't care about having the world make sense, they just wanted to spend money for their agenda. If anything, the best takeaway is to realize that whatever companies are doing now with race swapping and gender bending, just go for what was in the past.
We have tons of classics from the past. We haven't had many classics in the last 30 years or so. That speaks volumes. Not to throw the 90s under the bus, a lot of good came out of that time, but that was when world building was on its last limb.
The main reason is because modernism allowed the writer to work with emanation and postmodernism is a rejection of that.
Emanation has you go from the most broad concept towards the little things. Postmodernism begins with the little things and makes a structure with the broad concept maybe appearing.
Modernism was inspired by stuff like religious stories and romanticism which allowed it to all fit in a secure structure that a culture already was attached to.
Postmodernist stories now are more like "hey, I have an idea, and it's a rejection of what was popular somewhere. But it's okay because I'm adding minorities, so I'm sure the majority will care."
I can go on if anyone wants more information on any of the matters, but as you can see, the sperg aspect is attached to current postmodernist nonsense, despite the fact that postmodernist stories can have good world building when the person knows what they're doing. The problem is getting the postmodernist to pick a damn direction to begin with that isn't just pure propaganda and indoctrination.
