If city limits are removed... I'm afraid I'm going to require your home address Joseph... and all the people that took your side... so that I may do hidieously illegal things to you all for managing to make this mod completely unplayable for no reason. Please stop making me consider such things.
Seriously... its an option so power gaming diety players can choice it. Inflicting it upon those of us that may accidently try to enjoy the game as anything but a constant blitzkreig of war and madness suffer is just cruel.
I will now explain why. I'm an eternity player. I play enormous maps with 50 civs and continents. This means the map can literally hold hundreds of cities. I've had the AI Civs spam cities so hard they start overlapping ring one squares. This is with city limits on.
1. See the thing is that city limits keep Civs from doing nothing, but spaming cities and using them to spam more cities... to spam more cities... to the point the all start demanding Open Borders constantly for the sole reason of adding a city on a single square of unclaimed space in between four of your cities. Suddenly you have this diplomatic migraine of a huge negative multiplier from overlapping borders.
Then the AI does that again and again until it declares war on you... only its so over built that it only has stone age units... and that stupid 1 square city is auto burned and now you have a 'You burned my city!' perminent negative to relations for each useless city the build inside your borders and you are forces to burn their Civ to the ground so they don't endlessly pay other Civs to declare useless war on you. Giving you more permenent negatives to relation as you 'declared war on my friend'...
2. If they keep spreading out endlessly they keep contacting each other and even if you only met a single Civ... the AI loves trying to get you to pay them to introduce you to another Civ. Then one gets the clever idea to constantly donate those contacts with other Civs to you... so that that new civ can constantly demand free stuffs from you to the point you spend 5-15 minutes a turn simply turning down their constant demands. There is no way to cut ties with these Civs and a different one would donate the contacts to you if you did. Diplomatic isolation is ignored after 20 turns anyway... on eternity.
3. (v22) Then you get to the AI that is spiritual and takes over a continent as Spiritual is hidiously broken... I had a game with city limits on that ended when I was just getting to 14 cities and a spiriutal leader contact was forced on me... he had 45+ (going on 70 in less than 200 turns (14000+ turn on eternity)) cities and was donating every contact he made to literally every Civ and the game turns were 15-20 minutes each... mostly from trying to process 30+ civs worth of threats and demands with each other.
---Short answer--- Making every game require permenent war to not take 15-20 minutes is fun why? That kills over half the programming of the game.
