Which mod? I'd like to include it. I added more units capable of enslaving in my mod and activated sacrifice (have to see if the AI uses it though....) But I use the slaves (and later the Prize Ships) alsmost exclusively as workers (and the boats as transports) because they are free... The cultural expansion seems more a landgrabbing thing.... maybe it's the level or style of play. I'm mostly a conquer the land kind of player and don't play much pangaea. very true words. Most of the games try to go Despo -> Republic/Monarchy -> (stay in one of those) / communism. There are rare opportunities to use fascism, feudalism or democracy, but these are specific situations.
