I suggest making an update in politics & war which would make the approval rate play a role in your nation. I got this idea after feeling like the game is a bit unrealistic. My suggestion is to make it so that the approval rate can effect the crime rate, taxes and perhaps even the military. For example, if a nation's approval rate is 0%, most of the population will not pay taxes, crime rate will increase and perhaps troops leave the military and military vehicles get sabotaged. For another example, if a nation's approval rate is 75+%, some of the population will be donating to the nation (like a voluntary increase in tax), crime rate will decrease and maybe the troops' enlistment limit becomes higher than usual.
My idea, if done, can be changed a bit as it is just a suggestion and that's all I have to say. Thank you for your attention
