Im all for giving the Union the OOB it deserves, think it is mostly monetary/recruitment issue, hope the CSA also gets some tweaks.
But to the ideas.
I think Missouri and Kentucky need to be more contested issues, Union has to keep those states at all cost or risk defeat.
Add more NM losses to the Union for loosing Jefferson City, St. Louis, Louisville, Lexington and Cincinnati, maybe others?
Some cities/towns in Illinois and Indiana?
Maybe Kentucky should be possible to turn Confederate by invasion until some conditions are met by the Union?
The result should be that if the CSA threatens these the Union has to react, this is not Sherman breaking free from supply lines, Union has to keep these states under its control at all times.
I found that Louisville maybe needs some starting industry, the farms and shipyard at least?

I think the industry and agriculture regions spread out the war more realistically, they become targets and small side theaters, potential with those.
Please comment.
