I may be nearing my population maximum @ 1778 AD / turn 354. Adding about 20 population per turn or so, and CA II has just a handful of cities growing each turn. Research is off, and the lux slider is @ 50% and all my tile working citizens are happy at this point. +91 points per turn the last few turn, up from the low 80's. When I put the data into his calculator, Sir Pleb has us creeping up a bit every turn and we are projected to have over a 21k score at this point, #40 on the histographic chart, and the #2 Large Deity score. I don't think #39 / 22k is going to happen at this point.
I just went through all of the cities that generate culture for me and double checked that I would not get any unwanted cultural expansions. I am 1 tile away from the domination limit, per CA II, and I'm not going to turn a good histographic game into a bad domination one. So we sold off some libraries and temples just to be sure.
1960 tiles and 2597 citizens at this point in 1778, up from 1942 tiles and 2186 citizens in 1745 (turn 339 - 16 turns ago). I didn't search for a maximum domination limit for this game, I just wanted lots of river cows to give myself the best possible start for a win. So I'm completely sure that a better milking strategy would have turned out better, as well as faster conquest. But I'll be honest, I don't know how much quicker I could engage in wars the way I do and do the conquest phase faster. It would require a radical re-thinking of my methodology. My conquest phase this time vs. my 100k game was 6 turns faster (1590 vs. 1620), and I'm sure the first Egyptian war could have been conducted better, but there isn't going to be any 400 AD conquest dates for me.
