I think one of the more disappointing things about RWBY that probably only i have ever thought of, is the fact that the majority of the continents are in tropical/subtropical/arid areas, with temperate climates realistically being more rare than they seem to be in canon
Like,, the continents are mostly around the middle of Remnant. They're huge (I'd say Sanus is the length of the Americas on its side), but mostly around the middle. I can't say for sure exactly what the climate situation would be (especially because ocean currents affect climate and i have NO idea how that works), but realistically? MOST of the land on Remnant would be tropical, subtropical, and arid. The black dragon continent is basically in the same place North America would be.
Do you know exactly how much that would change things in terms of culture, food, etc? Apples would be a rarity, meanwhile stuff like guava would be more common, assuming Remnant has the same foods we do. Then theres animals! Theres obviously different animals in different climates, and that affects the kinds of foods people on Remnant would eat.
Different climates would've been SUCH an interesting way to set up unique kingdoms that aren't like, European-based Fantasy Kingdom #6263575257 (I hold a grudge over how Vale is depicted purely bc its my favorite region).
Like,, what would be considered a delicacy? What would be normal? What kinds of environmental issues do they have to protect against? What foods do some kingdoms have that other kingdoms don't? Were wars fought over these rare resources? Etc etc
Stuff like climate and region informs SO MUCH about cultures and their histories. Like,, did people fight over Vacuo not just because of Dust, but because they had the rare delicacy of chocolate? Is the history of coffee beans different from ours, where it was always normal instead of having a history of colonization? Do different kingdoms eat more meat from say, deer, vs cattle? Is seafood more common since a majority of the kingdoms' capitals are around the sea? Is mountain goat a common meat in Mistral?
And what about maybe animals and plants that are unique to Remnant? How do they impact the cultures around them??
Like, I'm mostly talking about food and diet, but this goes for a lot of other things. Materials like various minerals and metals, or different types of wood, or plants that can be used for other things like medicine or dyes. Or other stuff that affects cultures, like the weather and the seasons and natural disasters. And this is completely ignoring how the Grimm might affect all of these things.
Like,, the kingdoms in RWBY could've been sooo much more unique and I'm a little bit disappointed that they aren't
