I've owned this game for many years.. so long I don't even remember .. pre-2000. To the best of my memory, this game occurred when Sid and the Civ people were having a bit of falling out.. so Sid moved to Fireaxis and produced this game which built into it many of the "improvements" that he forsaw for Civ.. it was in some ways a "pointer" to CIV III and some of the changes to occur there.
