I used to have a list of government types you could choose from that would give many attributes that added bonuses to your country. After much testing and playing I decided against a choice of government but instead decided on creating various types of Generals from all forms of media ranging from video games to TV to Jesus! I got the idea from various games that had leaders and they add a good twist to the whole game by having their abilities used on the various units available not to mention boosting the economy within the game so units could be bought quicker than before.
