I'm in a Rising Tides map with you.
Know what would be cool, of course take missiles and commanders out of the equation, if when you take over someone’s land and don’t kill all their naval units airforce or ground units. You take every bit of their land until they have no morale left that you get to keep their army, adding a twist that they lose a significant amount of health and you need to pay in-game cash to repair 25-50k and there’s a certain wait period like military jail basically, also adding that the ones you haven’t researched that are possible ranks above get demoted to the ranks you have researched so it doesn’t make it too easy. It’s like they have to surrender…. I think this would be a cool touch to the game giving it a bit more realism.
