Played at the union side. A nice scenario.
some points:
At the end I had a tremendous amount of money (1000+ dollars), and all units bought. Loads of replacements, though I did not buy any myself.
I noticed some forts, sometimes, get a garison when enemies arrived, some dont and surrender at once. (Lost Sumter to a 18pwr strong cavalry unit, had to storm other forts, but also got one "for free").
Bought all militia units (state militia and volunteers) only to notice later that they could not move out of the region they were build in. They don't show this (no lock), but when you try to move them you get a "this region can not be reached" message).
It hurts that you need to leave an infantry unit in Los Angelos to keep it on your side. The locked cavalry unit (and the 10 militia) I had there don't work. I realize this is the way it works in AGE games, but needing to keep the strongest unit of the game in a town as garrison, just to keep it on your side, is not nice

.
I forgot: I also had about a hunderd .tmp files in my waste basket. Don't know why they go there after being displaced/discarded, but it is less than optimal in my opinion....
