I've seen people say they want giant stacks, and others say they like 1 unit per hex. But honestly, when you have a lot of Civs at prince level and above, 1 unit per hex is awful. The map becomes a solid mass of units. There is no longer any strategy whatsoever. In my current game at Prince, 75% of the giant world mass is occupied by units. Movement and management of armies isn't just a nightmare, it's impossible with so many differing political setups. My solution, is 2 units per hex for the following reasons: #1 - The graphics engine can already handle it (workers coupled with army units) #2 - The AI can, to a certain extend, already handle it. #3 - You can still bottleneck areas, yet you've potentially free up 50% of the tiles for movement. #4 - As in real life, you could easily cycle units to the front as opposed to how it works now. #5 - The AI would be much more capable at higher difficulty levels with stacked high level units. #6 - Lots of units does not equal intelligence. It just means more tedium. #7 - Turns could potentially be faster since routing would be easier. #8 - Stacks of Doom would not be game-breaking, but you'd still have the ability to have a premier fighting combo. #9 - Having units on almost every single tile on the whole map looks stupid, plays stupid, and ruins the game.
