Hey yall it's been a while, busy.
So I did a little more research and found out a way to refine climates by latitude to a point I didn't think was possible before. There are 4 settings for climates in the map, as well as 4 general latitude regions, but for whatever reason I didn't consider using the polarfront latitude as a temperate latitude before.
These settings I've uploaded set up 4 general regions - the Tropics, Subtropics, Temperate, and Boreal.
The Tropics are going to be heavy jungle near the equator, from about 22 degrees N to 22 degrees S. Jungle start civs should spawn here just about every time, like the Mayans.
The Subtropics are going to be heavier on desert, just like they are on Earth. There should be flood plains, oases, etc. and civs like Morocco, Arabia, etc. should start there. This will roughly be from 23 degrees to 35 degrees N and S.
Temperate is going to be where plains, grassland, and forests mostly reside, along with tundra the further you go north or south, similar to Europe, East Asia, and how the northern United States and southern Canada are. This will be from 35 degrees to 62 degrees N and S.
Boreal climate is where ice and snow are, from 62 to 70 degrees N and S. In order to really have regions like this, I adapted the map settings so that landmasses do not skip these latitudes. Russia isn't really Russia without Siberia right? Neither is Canada without that massive northern area. There is still room to circumnavigate the world up north or south though.
The trick is temperature settings. Even though the polarfront setting was designed for the boreal climate, I have the temperature settings divided into 3 major settings. Desert minimum temperature starts at around 35 degrees, making Mediterranean climates a thing. Jungle minimum starts at 23 degrees. Tundra starts at around 50 degrees. This makes for North Africa, Middle East climates, Congo & Amazon rainforests, and Northern Europe / Siberia regions.
This is in contrast to the way it was before, which did not include a Subtropic region. There was a general "horses" latitude that included everything from subtropics to the arctic. This isn't how climate actually is on Earth - the Subtropics is how the Southwest US and Mexico is so dry, along with N Africa, Middle East, and Southern India. I also aligned monsoon winds with the latitudes they coincide with IRL. This will make for even more diverse subtropics than before, since that latitude region is also where the monsoon winds are.
The end result is probably the best Earth-like maps I've seen randomly generated. Each region fits the mold, and trying to conquer the world like this will be interesting to say the least.
Just copy and paste the text file's settings into the Communitas.lua file in the Mapscripts folder of the Community Patch
Hope you enjoy the results!
