Well, the planes ARE too op (i can't get enough and spend millions on them, then a nation attacks and wipes them out in a single turn)
But you need to figure out a way for weaker nations to get out of a war with a stronger because i have 8 cities (soldier cap is currently 120,000) and im being destroyed by nations who are 'equal' or 'close to equal' in strength. No. They have 11 cities and 200,000+ troops, and i can't beat that. So we need to make a 'surrender' option in wars
people will abuse it if you don't regulate it, so do something like "You can only surrender if you have _____ less than your opponent's ______. Or something.
(Just wanted to say that because it is REALLY pissing me off)
