There are a lot of civilizations I don't consider 'real civs' in the game. I won't list them to avoid debate =). The thing is, I want to avoid them spawning in my games, yet I still want the civs list to be random. How can I achieve that? Is there a mod for this? I think I saw one at one point, but cannot find it anymore.
Along all the other awesome features for setting up your game this mod will give you an option to choose the active civilizations that can appear in the game...so you can disable those pesky Mongols once and for all xD.
"Select Active Civilizations: This allows you to determine which civilizations are active. Deactivate the civs that you don't want and they won't show up. Even when using randomly selected civilizations. "
