I would love to see a game that accurately reflects modern geopolitics. It would generate a world and run a history up to a certain point, at which you'd take control as head of state of a particular nation and conduct national affairs.
Ideally, the game would be able to make conducting the affairs of a large global hegemon like the United States as interesting as playing a small kingdom beset on all sides. Sort of like Crusader Kings but set in the modern world.
The real interesting part of the game in my view is that conquest is no longer an option, and tactics would get abstracted out of armed conflict in an "amateurs think tactics, generals think logistics" kind of way.
