Increase Number of Players/AI Opponents in the Game

Looking at the game and some of its mechanics such as vassals, it becomes evident that the game is better suited to a larger scale with more opponents in each game. With vassals for instance, there seem to be too few opponents to support this and it is currently too powerful. Similar to Stardock's Galactic Civilization IV: Supernova, the game should be able to support around 100 or so players/AI. Of course map should also be increased accordingly to accommodate this change as well.
