I'm playing War of Rights for the PC. Its a first person shooter, set in the Civil War. Yes, you heard that correctly. Yes, it takes like 20 seconds to reload the musket after each shot. The maps are all the little engagments from the battle of Antietam.
While this may sound excruciating to some, it is awesome. Your team is penalized heavily if you run off and Rambo if, and no score is kept for kills- it is just win or lose. You get no feedback from shots if you hit or not (just like real life) .Officers and NCOs use voice chat to command units, and they draw lines on the field for the unit to line up on and manuver around. There are also bayonet charges of course.
The game is still in development so there are glitches and they have yet to add artillery and Cavalry, but this is an incredibly fun game if you are into war.
