There are many settings to help the AI but I have a strong suspicion that some can actually hurt the AI. For example giving the AI the capability to see at an extended range appears to cause the union AI to send raids very deep into CSA territory though the mountains of WV, Kentucky and Tennessee. Also giving the union lot's more money, conscripts and supplies sometimes leads me to have super powerful leaders where my morale shoots up to 150-170 just from battles. In looking at some of the numbers I have captured more union soldiers than I lost. And killed union soldiers at a 2.4-1 ratio.
I'm not saying the game is easy or that I even play it correctly. Instead I'm thinking that in trying to help the AI with various settings I may have actually hurt it some.
So what would people suggest as a hard game playing as CSA be. And what would be a hard game as the Union be?
