So I have been playing this game for a while and I really enjoy it. However, there is one problem that I seem to be having and that is keeping people happy. I know how to build special buildings like circus, Coliseums, harvest luxury resources, have one unit to defense, and adopt special social policies. But for whatever reason my happiness seems to go down in my civilization. I think one of my reasons is that I keep expanding and settling cities too quickly. But I mainly do this to keep up with the AI who settles a lot of cities like 6 or 7 when I still have 3. I mainly play on Warlord difficulty in this game but I would really like your advice on what i can do to improve my happiness in the game?
