I've might have brought this game up to some of you at one time when it was in devloment. Anyways it is an awesome RTS set at the battle of Bull Run during the American Civil War. It was made by a bunch of Civil War buffs, so accuracy was a primary concern. The game is tacticaly superior to Total War. Ofcourse the Total War engine was made with a different type of warfare in mind. Nonetheless it is a great game that will feel familair to all us ntw player.
The only downside is that its only one battle(with many scenarios). And it lacks custom battles. Although from what i'm told the game can be modded easly. So while it does lack the verstile style of battles NTW gives us. On the other hand it is a game engine better fitted to our prefered era of war.
I suggest every take at least a look into the features of the game and read the forums/reviews. And most importantly its cheap!
