I have an idea, where there can be wars that happen, and you can be deployed to go fight in those wars. I’ve noticed that there are some random events that happen and is says like X country has halted their war with X country. Deaths measure in the thousands. Maybe with military, you could take the minesweeper game, and be required to stay in that country for a certain amount of years, before you are sent back home. There could also be like different names for wars, such as if Britain were to get in a war with Canada, it could be called the British-Canadian war, or if the entire world broke out into the war it could be called WWIII. Then once you retire or get discharged from the military, you have occasional pop ups that come up and is like “while walking down the street with your WWIII veteran hat on, a man thanks you for your service. How do you respond”? And then once you die, it could list on the tombstone what wars you fought in, and for how many years.
