I still have a CD of that game! It is very worn because of (probably) hundreds of hours that I played it from 1996 to 2005. There are visible "tracks" engraved on it (by the internal laser reader?). Since then I've gone through 3 or 4 PC's and Windows versions, and I'm currently using a laptop -- not sure if it would even work any more. Maybe I could still play it if I get the CD "restored" and if my current Windows OS can even read it.
It had four maps, all set around the historical times of exploration, colonization, revolution, and warfare from about 1750 to 1830. It included historical scenarios based on the actual history of those times.
Maps: 1) World
2) Asia -- roughly south/east/central Asia, China, Pacific coast from Kamchatka to Borneo, India/Pakistan, Japan, Indonesia, Philippines, etc.
3) The Americas (Atlantic coast roughly from Canada to Venezuela, and inland as far west as the Native American lands (Plains in NA; Mexico; Amazon in SA) but not extending to the Pacific coast.
4) Europe plus parts of Mideast and N. Africa (the biggest map, with about 170 territories).
It had a lot of great options including Fortresses, Capitals for victory, Generals, and "Fog of War". The graphics were tailored to represent each nation or tribal coalition. It also had a very clever AI which was hard to beat in a 5 or 6-player game.
