I just thought I'd post about a the next game in a series of games that has a very good AI. It's a strategy game for the American Civil War and is single-player or play-by-email. The developers are very good and pay attention to their players and post in the forums often and release patches rather quickly. The game is the result of expanding on a good base from thier first game, Birth of America. The attention to detail and the strength of the AI are two of the best qualities of this game.
Here are thier forums, go have a bit of a look and see what you think.

The game doesn't have tactical battles like TW, but the strategic AI is really well done. There is some complexity to the game, but it is not overly done. You don't get bogged down in micro-management.
However, I think you should have a look at the game concepts to get a feel for things. They've put the manual out on the web for people to look at and it gives a good taste of the game. You can find the manuals in the file library section of the forums (link above).
Have a look.
Cheers,
