OK, I think I've gone past junkie status here. Ordered another wargame today - Campaign Gettysburg by HPS Simulations. I'm enjoying Campaign Shiloh, so I've decided on slowly collecting the series.
If anyone is willing to buy the games, I'm willing to play them with you over TCP/IP or by email. Just drop me a note and we'll start a game.
Also, I'd like to mention that Brett Schulte has a Web page devoted to the Campaign series games that is worth checking out.
