Personal Requests:
Maybe you can upgrade your factory to be a military factory which helps or produces divisions or civil factory which gives more gold?
Transport ship for divisions on water so it is more realistic?
Maybe territory morale and if its below a certain point that territory either resurrecting dead countries or it will go to someone else with mostly high territory morale?
Make naval warfare more important at least to the bots (it feels like a unnecessary thing to have because if the country is weak enough to hide in a remote land it could just be easily crushed in late game.
Add capitals and if they are captured the country loses a random territory that is bordering a country unless it is the only one.
