On a continents map, is there a good reason NOT to slaughter every other civ on your continent? Playing as Sumeria I tried a 'peaceful' game, just to see what would happen. There were three other civs on my continent (France, Aztecs, and Sythia). No one declared war on me, probably because I had a good army. But the other civs kept flooding me with religious units even after 'promises' to stop converting my cities, refused any decent trades, kept denouncing me, and finally kept trying to squeeze in cities in tiny spots of land between my cities. So I just got tired of it and restarted close from the beginning of the game. I built 5 war carts and two slingers, and wiped out everyone. First the Aztecs, then France, then Scythia. Now things are much more peaceful.
