Most Populous Cities you've had

I'm not very good at growing cities; it's something I keep meaning to work on, in fact.

I think in a recent culture game as Ethiopia on King I got Addis Ababa to 32. It had Hanging Gardens, Artemis, Petra and ALL THE FARMS.

Turn 350-ish: Emperor, Lakes, All Standard except Raging Barbs. Tenochtitlan had 45 pop in my last game. Missed out on critical food-related stuff: Temple of Artemis, Fertility Rites and Hanging Gardens.

I'm tempted to try again, only this time, I'll go on a Sandstorm map, Prince, no Barbs as Netherlands. The map size will be Standard. Or do it again with the Aztecs on a lakes map again. The thing with the Netherlands is that the massive food bonuses will only come a bit later than Aztecs.

Key to massive pop are:
Terrain: Wheat, Sheep, Cows, Deer are favored. Much better if riverside. If you have a lot of wheat around you will benefit very quickly from an early granary.

Religion: All food-related stuff. Fertility Rites as said a while ago is a great bonus. Feed the World looks good as well if you really want to push it, but if you're going for a tall one-city nation, I think it would be a bit redundant.

Buildings:
Granaries, Watermills, Hospitals and Med Labs. You'll want to get to these as fast as possible.

Wonders:
Temple of Artemis (10% bonus), Hanging Gardens (+6 food).

Luxuries:
You'll be needing trading partners for your We Love the King Days.

SP's:
Obviously, go for tradition. The earlier you complete it, the better, since you're gonna need those Aqueducts. The sooner the higher the end population.

Accidentally loaded up another Aztec Game, Small, King, Standard. Found Skilldorado while starting on a VERY fertile ground. It had a nice stretch of river, enough for I think 7 or 8 flood plains.

Got all necessities: Fertility Rites, Swords into Plowshares (though Cath and Sully makes that a bit moot), ToA, Hanging Gardens. Surpassed 30 pop by turn 120. It was INSANE to say the least. I actually have unemployed citizens because my pop grows faster than I can build specialist buildings/grow culture borders!

Initial research is Archery, so I can build an early ToA. Almost managed to get Rationalism the moment I hit Renaissance (only 3 turns! If there hadn't been a two-way DoW, I could have gotten it). Get Lux Techs, then The Wheel for Floating Gardens. After that, get Philosophy for NC, beeline Civil Service, then Education, then Acoustics. Even without much hammer tiles early one, the sheer amount of people Tenochtitlan creates is enough to cover for it. To the point that I wonderspam and just buy buildings!
