Civ II Gold has a lot going for it. It has an editor. It has a lot of variants from fans. It has actors portraying your advisors and changing costumes and mannerisms as you enter new epochs. For those who are so inclined, it even has a cheat mode. I play Civ III a lot with some additions I got off the inet, but I really miss the advisors, the caravans, the dinosaurs, and the gods.
