I gave a talk at GDC 2004 on maintaining successful franchises, with a focus on the Civilization franchise. This talk was the first time we gave any significant public details about Civ 4, so it’s interested to see what I thought was going to be important over a year before shipping. Unfortunately, the talk was not filmed, and because I always wanted to get it online, I went ahead and reconstructed it from the original audio and slides. If you give it a watch, let me know what you think!
