Growing a city to size 28 or higher isn't really that difficult.
I think the OP's original challenge is to have a 'lot' of size 25+ cities, not just one or two. With the added challenge of higher difficulty levels.
I gave this a go myself last night on Emperor, Huge map, Continents as I haven't had too much trouble getting a half-dozen or more size 20+ cities on King or below. I tried a game as China and thanks to the Paper Maker and plenty of grasslands + river I had what should have been a great starting area for this. My starting Warrior got bumped up to a Pikeman thanks to a set of ruins so I did an early attack on Persia to my north to wipe them out since they were extremely close to me. After that I was ready for some concentrated peaceful building since everybody else was down to the south and east of me.
The two immediate neighbors were the Mongols, Japan, and Egypt. I decided to try and be nice and butter up the Mongols as much as I could since I didn't really want to war with them ever. I took this to the point of even joining them in a war against Japan so that I could stay on their good side. But of course, as soon as I had a common border with the Mongols our relationship immediately went under and he attacked me... and to keep friends with him I had even just agreed to his GPT demand shortly before. Aside from this war, Ramses and Elizabeth started sending me insults and eventually declared war on me too. At this stage there was still 4 tiles in between the borders between me and Egypt and I hadn't even found Elizabeth's homeland. I found out later she had to march through both Roman and Egyptian territory to get to me, so I don't understand why she wanted me dead. I'm only guessing that somehow the AIs were persuading each other to go to war with me.
So by the time 100AD rolls around, I'm entering a phase where I am always at war with one or more AI players, and they almost never want me to make peace with them. In the case of the Mongols, I couldn't even get a peace offer until I had taken something like 6 cities from them. Since I didn't even know where Elizabeth's homeland was I had to bribe her into peace by giving her one of the Mongols' cities and tons of my spare luxuries. Ramses *never* made peace with me, even though he didn't seem too interested in actually prosecuting the war. Once in a while a couple of Knights and a Swordsmen would wander by to my closest city to them and I would have to deal with that, then nothing for 10 - 15 turns. Honestly in situations like that where no blows are exchanged for so long I don't know why you can't get the AI to agree to a white peace. In the case of the Ramses AI, he wouldn't even open up the trade screen after I picked 'Negotiate Peace'.
By the time I had done with the wars vs the AI players that were actually serious about sending armies over to kill me, it was passed 1400AD so I gave up on the game. Having to beeline Chu-Ko-Nus so I could stay alive wrecked my chance at having Civil Service or Biology in a decent enough time frame. I gave up on finishing the game since I knew I wasn't going to be growing any super-cities here which was the main point to begin with. I also hadn't been having any fun for the last two hours as I realized that the wars were never going to stop, ever. Ramses also had Renaissance troops out and Himeji Castle out so I saw it was too late to make a dent in him.
So some questions for the folks contributing here-
For the ones who are casting a dim view to the 'warmongering' exhibited by others who have discussed their games in this thread, how exactly at higher difficulty levels can you pull off a game without having to find yourself eliminating one or more opponents? If you don't have your landmass to yourself (or well over 50% of it) what are the tricks to living peacefully? In my game the only reason I attacked Darius right off is that I *knew* he would be the first to attack me since he was the closest neighbor and nothing at all I did would make any difference. With the diplomacy setup in Civ V you're always going to be at war, it's just a question of when (and again to make it clear, I'm talking higher difficulties). So far my only peaceful games have been at the lower levels where I assume the AI is either programmed to be nicer or they are just afraid to attack me since I'm so far ahead of them.
For the builders, thanks to the Paper Maker I did have a decent cash flow going for a while in the early game. I'm not sure what the optimal way to spend it should have been. Once I was at war, I had to pretty much sink all the money I collected into unit upgrades and troops to stay alive. Before then, I was trying to prioritize RAs since I assumed that on Emperor level I wouldn't be able to keep up in the tech department without help. As a general strategy, do you think this is helpful, or maybe I am better off buying more buildings or saving for City State alliances?
I also noticed after a while that my cities hadn't expanded their borders out as much as I usually see, which meant that I wasn't filling in my map area as much as I think I ought to and giving the AI more room to plant their famous and war-provoking (because you are now to close to *them*) 1-ring cities. Are the culture costs for a city to claim a tile also increased? If so, maybe I would have been better off using my cash surplus to acquire more Temples since the Monuments were too ineffective at this level? Or, maybe it is more helpful to use Washington and/or Monarchy so that you can use your cash surplus to buy tiles instead of Temples. Or stick with France to help solve the early culture problem. I'd hate to give up China though since the Paper Maker is such an awesome building. Any thoughts?
