Bought Campaign Shenandoah based on the review here. Good game. A couple of minor issues, some of the keys for accessing features, such as the manual, do not work. Not too much of an issue as the manual can be accessed through file explorer.
The graphics are good. Unexpectedly, I have prefered playing with the unit symbols showing instead of the unit icons. Probably because you get a better top down view.
I have a difficult time determining combat (defence) factors. I had placed troops behind (stone) fences and on creeks where that attack factor discount was 0%. I would have expected that troops behind a fence would get a defensive bonus. Troops attacking across a stream should receive an attack discount (or units on the defence, a bonus). But, I couldn't determine that. (Pressing F2 does show combat modifications.)
Many many years ago, I had bought Campaign Chickamauga. I mention this because Campaign Shenandoah seems to be based on the same game engine. There may have been some evolutionary improvements (graphics are better) since the original release of Campaign Chickamauga.
As an aside. I am using LINUX as my principle operating system. I do have a dual boot computer. So I will have some opportunities to play turn based simulation games such as Campaign Shenandoah.
