Question regarding the Alpha Centauri series (Score 1)

I don't buy a lot of games generally because I find very little replay value in most of them. But I have to say that Alpha Centauri (and Alien Crossfire) are the best games I have ever bought. You can't imagine the fun I had (and still have) playing just the single-user mode. It is very unforunate that (I am a Mac user) I was never able to find anyone to play a multiplayer game, either because of bugs in the application itself or because of a lack of available players. In any case, I was wondering if you have ever considered a follow-up to those wonderful games, maybe something more in-depth with deeper social and political aspects (I loved how they intergrated into the game). I should say I've never been tempted to play any of the Civ games. In any case, kudos on all of your work and the people that have helped you in making it happen. Thank you!
