I stick to boardgames and there are many excellent Civil War simulations out there. I'm just setting up a new, very simple game on Antietam by White Dog Games--beautiful graphics. GMT games is reprinting their U.S. Civil War, which will remind you a great deal of the VG Civil War game, and they also have updated AH's For the People. MMP games continues to publish the Great Campaigns of the Civil War series begun by AH--including Sherman's Atlanta Campaign and Hood's Tennessee Campaign, as well as a series of regimental level treatments of battles. For a great system with interesting battles, check out the Blind Swords system mostly published by Revolution Games--they just published games on 1st Bull Run and Wilson's Creek. Boardgamegeek.com and Consimworld.com are great places to search for games--and the former has a marketplace feature where new and used games are sold.
