Funnily enough, there was a redditor 10 years ago who was playing the same civ 2 game for a better part of a decade, his game was a irradiated hellscape that had nukes flying the moment a civilization expands. 

Look up the eternal war civ 2, it's a fascinating read

It was such an interesting game that story made it into Sid Meier's autobiography.  Imagine that.   Your game was so unique that one of the most influential game designers in history put it in his autobiography.   

Not a bad read by the way.
