Most people are aware of the extensive modding capabilities which there are in Civ. Starting from Civ2 we had great scenarios, space and fantasy mods, everything what you can imagine.
But did you know that you could already mod Civ1? Our user blake has made a compilation of the available mods and scenarios for Civ1. He uploaded 11 scenarios from Civ1 to our database. The list includes a Rise of Rome and a WW2 scenario, an earthmap, a Dune scenario, and some user made fantasies.
