Take Command: 2nd Manassas PC game

I'm always interested in finding new computer games, and I've found one that had me up playing it till about 2:00 am last night. It's called Take Command: 2nd Manassas. It's a real-time strategy game, based in a 3D world. Some would probably find it terribly boring, but if you're into "Napoleonic" tactics, including battle lines, formations, wheels, blah blah blah, you'd probably enjoy this. Here's a link to their website with a free demo of it, which is all I've gotten so far.
