When we approached the editing tools for Civilization III, we were determined to offer a contemporary customization environment. In previous incarnations of this franchise, users were capable of making radical changes to the game systems, but often needed to locate and edit text files to do so. In Civilization III these changes are still possible, but can now be made within an application that follows the interface rules of standard Windows programs. This editor not only allows you to alter game elements such as advances, civilizations, units and wonders (to name a few), but also includes a robust map editor. Using the editor, users are empowered to create scenarios that we never dreamt of during development.
The editors in Civilization III are only the beginning. Based on feedback from the mod and scenario community we will make additional improvements and incorporate new features. The editors are just tools, ones that the fan community needs to make meaningful by creating new scenarios with. As those in the 'trenches' of creating new content run into limitations, we'll work on eradicating those barriers. Firaxis is very interested in Civilization III having an active mod community, but need to know where our efforts are best spent. Together we can make Civilization III a potent platform for not only exploring factual history, but also your creativity and interests.
