from the FAQ
The History Game Canada is a mod pack for Civ3 Conquest v1.22 and Civ3 Complete that is based on the History of Canada. It is intended as a playable fun addition to the Civilization game with a wealth of custom Canadian content. It’s very much a game of ‘What if ...?”; where players can toy with outcomes, now etched in history, but once hanging in the balance. It explores the parameters of history rather than the events, and allows players to live questions like … ”What if the Huron had displaced the 5 Nations Confederacy rather than the other way around?”; or “What if the French had retained Canada, and the English colonies to the East and South had failed to prosper?”
You’ll need a copy of Civilzation III Conquests (patched to version 1.22) or a copy of Civilization III Complete. Then you just have to download and install the game pack, check out the videos and resources on the website, and get started.
