I make it so you control a country in an era or time. It checks real data and uses different stuff I guess. Use different commands to invade, form alliances, check relationships, annex, puppet a state, etc. Advises the user and helps you check how many resources and military you have. Train troops, invade, make factories, towns, etc. Expand into different unknown areas in like 1559. The civilians can revolt so check on them. You need Resources to make. I Make sure the info is detailed.
