I'd like to recommend a very enjoyable light Napoleonic title called Musket Smoke. It features turn-based solo and multi-player options. It's "light" in that you have two generic belligerents and four unit types....pikemen, musket, artillery and cavalry. It's fun because smoke starts to cloud the field which actually impacts sighting, and bodies appear on the field too. When casualties get high, "gore piles" form which I believe causes a hit to morale.
Downloading now! Thanks for the heads up.
Edit - I think the game is pretty good. Only had a few chances to play it, but it looks good and the tutorials are easy to follow.
