FreeCol

FreeCol is an open-source strategy game inspired by Colonization, allowing players to establish a new settlement, exploit resources, trade goods and eventually fight for independence. Naturally, colonial administration turns out to involve considerably more paperwork than advertised. The game combines exploration, economics, diplomacy and military strategy, with a strong emphasis on managing a growing colony and making the most of limited resources. Its open-source nature has allowed the project to evolve well beyond a simple remake, while still preserving the basic appeal of the original concept. The interface may look modest compared with modern strategy blockbusters, but there is plenty of depth underneath. If you enjoy historical empire-building games where trade routes can be almost as important as cannons, FreeCol is worth a look.
