I'm dating myself again, but who cares? LOL My favorite computer games were by an Australian company, Strategic Studies Group (SSG), I spent hours on both the C-64 and Commodore Amiga versions of Decisive Battles of the American Civil War Volume 1: Bull Run to Chancellorsville, Decisive Battles of the American Civil War, Volume 2: Gaines Mill to Chattanooga, and Decisive Battles of the American Civil War, Volume 3: Wilderness to Nashville.
I think they're still available as "abandon ware." Lots of great memories...
