What happens when you play the same game of "Civilization II" for 10 years?

-The ice caps have melted over 20 times (somehow) due primarily to the many nuclear wars. As a result, every inch of land in the world that isn’t a mountain is inundated swamp land, useless to farming. Most of which is irradiated anyway.

-As a result, big cities are a thing of the distant past. Roughly 90% of the worlds population (at it’s peak 2000 years ago) has died either from nuclear annihilation or famine caused by the global warming that has left absolutely zero arable land to farm. Engineers (late game worker units) are always busy continuously building roads so that new armies can reach the front lines. Roads that are destroyed the very next turn when the enemy goes. So there isn’t any time to clear swamps or clean up the nuclear fallout.

-Only 3 super massive nations are left. The Celts (me), The Vikings, And the Americans. Between the three of us, we have conquered all the other nations that have ever existed and assimilated them into our respective empires.

-You’ve heard of the 100 year war? Try the 1700 year war. The three remaining nations have been locked in an eternal death struggle for almost 2000 years. Peace seems to be impossible. Every time a cease fire is signed, the Vikings will surprise attack me or the Americans the very next turn, often with nuclear weapons. Even when the U.N forces a peace treaty. So I can only assume that peace will come only when they’re wiped out. It is this that perpetuates the war ad infinitum. Have any of you old Civ II players out there ever had this problem in the post-late game?
