Maybe it sounds like Hoi4 and doesn't fit this game, but in addition to creating countries, changing terrain, and preparing for war in map editing mode, events happen when the time is right (e.g., civil war breaks out in Italy when it is August 2028...). If we could set up the details of this, it would open up more simulation possibilities and more mods, which would be a good thing.
Sorry for the long post.

A country named after the title of a Japanese manga, "Blue Rock," has been born in Canada. It's a miracle.
