With the way gem changed the game, it feels like culture and faith city states are extremely profitable if conquered early in the ancient-classical eras. Conquering a faith CS means an instant pantheon, even without building shrines. Conqueing a culture one just feels like one or half of instant oracle. This is on top of gaining one or even two luxury resources and strategic resources. Given how national happiness is usually in demand in most games, theres absolutely no incentive to conquer happiness CSs. Its better to save the city states so it gives you the much needed national happiness later in the game. Given how gem enhanced culture output, and faith output of buildings and wonders, the +6/+12 culture/faith is rather miniscule in the late game. Even playing as siam, i would rather conquer those city states, since the +25% doesnt amount to much,. Even if the UA were to double the CS bonuses, i would still feel tempted to conquer them. I havent tried conquering military CS yet so i dont know what effect it gives. Is there a way to balance the city states so that all of them are equally worth it to conquer, or equally worth it to save and develop relations with?
