New cultures are already in mod. You can find them in mods/my_mods/new_cultures directory.
I am going through fixing a bug in the Unit Schema file so will fix your New_Cultures at the same time.
Do any of these lower culture units upgrade, mine aren't?? attached are just a few examples??
3) You have a couple of stray characters on a couple of lines
May be that is something we will have to live with if Sparth's Cultures is to be used.
Does it still break saves if the Folder is moved to My_Mods (Unloaded)?

Which characters in which units?
They were a >= and a >>, I can't remember exactly where but in the later part of the heroes file.
Cultures are based only on your base region culture and terrain/resources at the moment. There are no restrictions by longitude or latitude.
This is because we had so few. I would like to see some changes on the requirements for Cultures now that we have quite a few. I think we could make things more interesting by having a few prerequisite Cultures of which you can only get a few. However a review of Cultures is a big task.
