Personally I find Civilization 4 to give striking insights into the development of world history, with diplomacy being one of the key elements. I remember playing, with the USA no-less, and sitting on a piece of land void of any oil. With time ticking on I sought the weakest opponent I could find and built a large, though somewhat outdated, fleet. I strategically planned a shock-and-awe tactic and managed to conquer the target city in a single turn. Then all the world hated me and the most powerful Civ declared war, wiping out my fleet in a single round with his well-fueled destroyers. Such is history. I lost that game.
