I just updated the Guide to include some of the edits that were proposed over the last week. Info on Great Musician costs has been corrected. I mentioned more on Tile Improvements (including Holy Sites from finishing Piety) and the three Civs that can innately construct Culture-producing Improvements. Additionally, there is a bit about the World Ideology resolution and how it can be helpful in pursuing this Victory.
Thanks! This does indeed fit, and I'll definitely put something in although I need to decide just how much to add because there is quite a bit to the system and including it all could push this article beyond its intended scope. At present, that information is included as part of my
Ideology Guide. That article serves as the gateway for Ideology selection at my site, which is a bit of a work in progress. I plan to add to that as I learn more about the game and improve my own play. As you probably know, we may encounter everything from a little Unhappiness from Dissidents to City-flipping from Revolutionary Waves. I think I will try to summarize it under the Influence levels section soon and link to that part of my site for more in-depth info.
