There already exists almost no incentive to actually kill city states. They don't need to be STRONGER.
Here's how maritimes should be nerfed:
The AI should be patched to more actively work towards gaining city state allies, especially maritime ones. They should compete for allies that you already have. We all know that the AI commonly sits on thousands of gold. Those AIs unable to win the friendship of maritimes should be actively attempting to conquer them, on the principle of "if I can't have it, no one can!"
Would we still consider maritime city states to be overpowered, if we needed to keep them at 300/60 friendship, and needed to keep 4+ good military units by them at all times, in order to gain the bonus?
There's been so much discussion on this, and I think the best 2 options that came out of that were
1: Making them give a +% bonus to your surplus food production (like a We love the king day effect)
2: making them give a flat quantity of food, divided evenly through your empire, rounded to the nearest .01
Both would need some serious testing to balance the exact numbers, and there might be unforseen effects. But farms are currently underpowered (in large part due to maritimes), so I don't think multiplying their output by a % would suddenly make them overpowered. Splitting a flat food amount would be great for small empires, which are currently much less powerful than large empires. Either way, you are strengthening a weak part of the game, which should theoretically work out well.
I'm really new to the game. Can somebody please tell me why maritime cities are OP?
The bonuses are cumulative, they increase as ages progress, and you can often ally with several in the same game. In later ages, you can get a ridiculous amount of free food - manna from heaven, basically - if you Ally with just three Maritimes, like +15 free food in your capital and +9 in every other city in the world. (I think that's the rate, but my numbers could be wrong.) That enables you to basically found cities anywhere you want; even a city in the middle of the desert will grow quickly given +12 free food.
In broader terms, this ends up almost negating terrain yields completely, and city development becomes pretty warped because your newly-founded cities can skyrocket up to major metropolises without any "growth improvements." Improvements like farms, buildings like granaries, and food-based resources like Fish all become meaningless. Might as well drop that Settler down in the middle of polar tundra, because that city is going to grow like it was surrounded by grassland / river tiles.![]()
Sounds pretty realistic to me.
The settlement at Jamestown in the 1600s entirely relied on food supplies from England until John Smith came along.
How about leaving them as they are?? As long as tile yield and city growth past size 10 is not adjusted, I would change NOTHING about the current maritime city states.
Also don't forget that not everyone plays on huge maps where you have dozens of maritime CS! I often play smaller maps, where you usually don't get more than one or two maritimes.
However IF something is done about tile yield and city growth, then I like the suggestion of changing maritimes to provide a science bonus similar to the culture bonus of cultured CS.
Maritimes are overpowered because their bonuses increase with the number of cities you have (thus making ICS easier than it should be), unlike the fixed bonuses granted by cultural and militaristic city-states.
The simple solution would to let maritimes grant X amount of food (or X*1.5 for ally status), to be distributed among all your cities. X should start low and increase significantly every era to prevent maritimes being too overpowered in the early ages.
Change nothing? Care to explain why in more detail?
As for number of them, on a standard map you will have 16 CS, for an average of 5.33 Maritimes. Hardly limited.
