How Hard Is it to Mod the Map?

[PalaiologosTheGreat]

I'm thinking of making a mod which makes a United Hispanic Empire. How hard would that be?

Not sure what you want to make, but mod the provinces TextAsset element to change starting territories of whichever countries.

I did myself try to change some province properties as well, like seeing if I can make germany anschluss Austria from Austro-Hungary, and giving Soviet Russia baltic states, and making relations bit more historical too, so that Russia is not for some non-existent reason friends with Germany, all for 1940 start.

Failing miserably in every department except for the relations one, for reasons I cannot see, so go ahead, try your luck.
