The Hittites just captured a city from the Ottomans. This city was very far away from the rest of the hittite empire, and it only had about 5 or 6 pop. I basically had the city enveloped with high culture producing cities of my own. I checked my advisor, and sure enough, hittites are in awe of my culture. I tried propaganda 3 times in a row (3 turns in a row) and no luck. I also tried it many other times throughout the game to different civs, many of them in anarchy, and all of them at least admirers of my culture. Also, I tried to pick the cities that were as far away from their capitol as possible. I probably tried 15-20 times throughout the game, and no luck. At 2 grand a pop, you would think it would have more success than this. Maybe I just don't know how to do it right. If this is so, maybe someone can enlighten me?
