I've posted this already in the 2K forums and the Bug forums here, but it seems this thread might be a more appropriate place. It's a rather big balance issue, concerning the maritime city states. I know other people have mentioned it too, but I think it's a rather important one to fix. And I can't see it on the list of issues in this thread.
So here's the issue: Especially playing with Alexander, the gold-food ratio of maritime city states is totally of the hook, especially in the later eras.
To take an example. Right now I play Greece, I'm in the renaissance era. I get 5 food in my capital and 3 in every other city PER MARITIME CITY STATE that I'm allied with. Now, I've unlocked the Patronage social policy tree and got an extra 25 % reduced cost on that food.
My relationship with the city states degrades at a rate of 0,37 points pr turn. I pay, in average 250/30= 8,33 per point. So I pay about 3 gold per turn for 32 food (5 in my capital city, and 3 in my nine other cities)!!! Of course, if I had more cities, I would have even better value for the gold.
Compare that to the yield of a Granary. 1 gold for 2 food, and remember you have to add the hammer cost. If I was to get the same benefit from a combination of granaries and water mills (2 gold for 2 food), we're looking at between 16 and 32 gold pr turn (depending on how many of each you've got). AND the hammers....
And if you switch farms to trading post adding up to 32 food, I can essentially switch 16 farms and turning 32 food into 32 gold! So by paying 3 gold I can get back 32 gold - a net yield of 29, PLUS I get access to the city state's resources. Compare that to switching farms for trading posts by building granaries and water mills (9*2 =18 food from granaries, 7*2 =14 food from water mills. Total 32 food), now I need to pay 23 gold maintenance, AND a hammer cost of (100*9 plus 120*7) 1740!! For a net yield of 9 gold!
Pretty awesome difference.... I know that the city states don't yield that much in the earlier eras, but they're still A LOT better than buildings. Even if you don't play Alexander. AND the city states will go to war with you. AND it can even directly help you win the game (diplomatic victory).
This MUST be fixed. Maybe they should turn the food benefit from granaries and water mills into some sort of percentage modifier, or make it increase with certain technologies. OR nerf the maritime city states - A LOT. Anybody else got an opinion on this?
