It's from a shovelware CD put out by Microprose around the time Civ2 was released. Has four Microprose games on it: Civ1, F117-A (a flight combat sim), Railroad Tycoon, and Silent Service II. I installed it the other day using DOSBox, and the Civ1 which comes with the CD doesn't have four civilizations that I distinctly remember playing in my original copy of Civ1. Anybody know why these civs aren't included? Are there any other changes to the game I should probably know about?
