I recently revisited Sid Meier's Gettysburg
and Sid Meier's Antietam
. Fun stuff: I'd forgotten how much fun it was to watch little brigades of men shooting at each other. The interface is too mouse-dependent for me, though. (I'm always having to move the mouse to the top of the screen, wait for the menu options to appear, and then click around to get what I want. Breakway games improved this when they adopted the engine for Waterloo and Austerlitz.
My initial troops, having driven off an opposing rebel force, are now being slightly outmaneuvered by reinforcements. (That was my doing, as I diverted a regiment to destroy the rebel artillery. This left my lines short.) Fortunately I have a brigade of fresh troops of my own. Together my two brigades will utterly ruin the slaver adversary.
