Score is a comprehensive measurement of a nation's economic and militaristic influence.
Score is the primary factor used to compare and rank nations against each other. The highest score nations and alliances are featured on the Leaderboards page.
Another primary use of Score is to ensure that only similarly sized nations are able to declare war on each other. This prevents very large nations from picking on very small nations.
The Score formula is determined by domestic and economic factors, such as the number of cities and amount of infrastructure a nation has, as well as the number of military units it has.
Score = ((Cities - 1)*50) + (Infrastructure * 0.025) + (Soldiers * 0.0005) + (Tanks * 0.05) + (Aircraft * 0.5) + (Ships * 2) + (Missiles * 5) + (Nuclear Weapons * 15) + (National Projects * 20)
