Well now, I'm new to Terra Invicta but I love this kind of mod that's just, evolving, based on our scientific and historic data. Props to you!

You should consider sharing the data from this in the TI discord - in my experience, the devs are often willing to take a look at adding missing things like this if you bring it up & provide some data/justifications for it!

@DeltaOne Not explicitly. In vanilla if you hover over regions you will sometimes see that it has a modifier that make it an "oil" or "mineral" region, with the associated economic bonuses. There is also a hidden modifier in vanilla that gives a region the chance to gain an oil or mineral modifier over time if you develop the GDP of the nation enough (not a lot of documentation on how this specifically works).

What this mod does is simply add those modifiers to specific regions that previously didn't have them. I went through and researched the real life mineral/oil reserves of each region and added the appropriate modifiers to each region based on this data.

what does this mod do? allows countries to produce resources?

Very unfortunate. I'll keep this mod in mind for my next playthrough.

@indyTheCommando It is not. you must start a new save.

Is this compatible with existing saves?

i had thought about asking for the coastal stuff and totes forgot. you the bomb
