I gotta share Tony's world-building advice. He's done a bunch of videos on every simple yet powerful economic factors that shape the formation of civilizations and cities and nations. Things that are often forgotten by D&D writers and Fantasy authors.
They're elements that make a world feel REAL, and don't need a ton of detail or work to implement.
His recent video here is on the Water Trap.
He talks about Karl Wittfogel's now much weakened theory about Hydrolic Empires, where water control creates tyranny, and about why it's not accurate and what factors ACTUALLY shape such civilizations according to other Anthropologists. Things like if water comes from rain or a single source like a river, can people just walk away or are they trapped because the only viable survival option IS staying in that area, are local bodies organizing together to manage the resource or is one ruler taking power over all local bodies?
One of his previous videos was about the Ox Paradox. Grin can be transported by Ox over a road, but the Ox needs feeding. So there's going to be a point where the food cost of the Ox is MORE than the amount of grain you can bring from your farm or community to a larger collection point/city/town/etc. So that's the limit of how far away food production can be from towns. That range is increased if the food being transported changes as well as if there's a river that can extend it. But that itself creates a power dynamic and conflict between those upriver and those downriver.
It's great stuff and a fantastic resource for anyone doing some world building. Because every source of conflict is a place where drama and adventure happens.
A perfectly balanced world with no conflict might be nice to live in, but it is a boring one for adventurers and stories to take place in.
In this playlist I go through my insights on worldbuilding gathered over the years.
