I grabbed a copy of Alien Crossfire, the expansion pack for Alpha Centauri, over lunch today. Now I can't wait to get home to play it. Alpha Centauri, like Civilization II, and all other Sid Meier games, is incredibly addicting. I've lost entire weekends to these games before, refusing to even pause to eat! I've been playing quite a bit of Diablo II lately, but I'm starting to get a little burnt out on that.
