When you form the CSA you lose ALL factories BTW.
Anyways, I have been playing as the CSA and it's 1870 now I think.
I won the civil war by turn military spending up to 100% and use mostly Dixie infantry. (lets pretend the military was mostly run by the south
Since then I have defeated the USA in not just one, but two wars. No cheats or using cheap tactics like the first one. They kept declaring war first thing our peace treaty expired. Now they stopped because my army is now massive, I think I have over 60 brigades.
And my economy is very well. I managed to stockpile 50k in money for the second war which drained it all, but now it is hard to make money as I get more and more craftsmen but there is an oversupply of every good. I only have Mexico and Columbia in my SOI, so selling everything is the hard part.
Spain and England will not become my allies with 200 relations, so defeating the USA will be hard, it seems after I killed a stack of 50k they make another one.
But unfortunately now I am plagued by the rebel problem. Every 6 months 90% of my provinces rebel which takes up a lot of my time and makes the game rather boring.
