I agree with what's been said so far. If you're serious about staying in the club, go for the 5 for 3 deal. Since there's only 4 ACW games, you can make the 5th France '40 [;)]. You can find some of the Talonsoft BG games here:
http://www.cdaccess.com/html/pc/49civil.htm I'd suggest getting at least one of those at some point just to experience the early style. You might prefer it as some do. Just make sure to get the patches and 32-bit upgrades from the club pages because those from Talonsoft prevent the 32-bit upgrades from working. There's also a patch for Chickamauga that fixes Talonsoft's copy protection that was incompatible with Win XP. Good luck and have fun!
