Using Sampsa’s excellent spreadsheet to make a differentiation:
3-city-saves (average of 6).
food + hammers : 19,5 (current production)
commerce – cost : 11 (current tech rate)
tiles improved: 3
2-city-saves (average of 9).
food + hammers : 19 (would be 18 without C3)
commerce – cost : 15,5
tiles improved: 5
This is an interesting analysis. I guess one concern of mine is that, at least as far as food+hammers are concerned, the 2-city saves are getting close to saturated with growth and tile improvements, so in order to improve in those regards they will have to spend time building settlers, whereas the 3-city saves have much more room for improvement and their modest food/hammer advantage will likely take off in the near future. As for commerce, I'm unsure of what the future teching plan should be, so I'm curious to hear what folks like Krikav and yourself plan to do with all of the extra beakers.
Another concern is that the very best and very worst saves from each group are lumped together, when we should probably analyze the strategies based on how the strongest results turned out. I'm going to pick out the saves that I think are the best from each cohort and do a similar analysis here.
I would consider Myself, Mscellaneous, Sampsa, and Wrathful (roughly in that order) to be the strongest 3-city examples to go off of.
Swordnboard: 21

/

, 14 net

. Progress on a fourth settler means productivity will once again jump in 5 turns.
Mscellaneous: 22

/

, (20 w/o copper pop), 10 net

. Completion of workboat will eventually reap large commerce rewards.
Sampsa: 17

/

, 12 net

. Also note 3(!) workers and 1T from piggies meaning many of these yields will improve quite soon.
Wrathful: 21

/

, 10 net

, but only one worker so I rate a touch below the others.
I guess what I see in these saves is an average of about 20

/

, and a lot of clear growth even looking only 5 or so turns in the future. As for the 2 city saves, while many linger around 18

/

which is pretty close, the now-necessary settler building process (ideally reaching 4 cities by T60 or so, for my own save I'll have a goal of settling city #5 by then) will halt progress in

for a little while. Meanwhile, commerce will slowly increase due to cottage maturation, but the two cities are aready operating near happy cap so not too many new cottages can go down.
For the 2 city saves, I'm noticing a lot of parity and have trouble picking favorites. I'll downgrade c^3's production to 16 (since getting double credit just for building the GW is a bit cheesy), although perhaps we should consider the doubled hammers as research output instead since they'll probably end up as failgold (but 2 cities = very low deficit so will take quite some time to spend the gold). Some of the stronger games IMO are Olafeson's 17/19, Krikav's 18/20, Powerfaker's 20/16. If you have a solid plan for the extra research and want to play Krikav's save, you may find issues with stagnating productivity as the necessity of workers & settlers catches up to you. Or if we look at Powerfaker's save and think of it as comparable in outputs to my own, why not choose the save with a "free" extra city?
Nothing really wrong with your save except Damascus seems to be...in an inexplicably trashy position?
Who knew my seemingly innocuous city plant could spark such diverse opinions... Krikav and Sampsa really like it, you rate it as one of the worst among all possibilities, and I myself will defend it but stand somewhere in between. I settled it with auto-connection and early hammers in mind, but 3N1E seems to do about the same in this regard (only 1 road required for connection), while adding a much needed second floodplain to the mix (this is actually much more important than the potential of getting stone with a border pop).
I'd like to see a really nuanced comparison between early-BW and this game, which looks to hit it around t52.
Perhaps we'll be able to see a game for that! Also curious to hear Fippy's take (re: Krikav's choice to do early pottery). Doesn't necessarily have to be powerfaker's save though; even folks like Krikav who have BW but have been building improvements instead of chopping can serve as a comparison point. Worth noting though, is that despite my maniacal chopping spree, I still have 7 forests under culture, same as Powerfaker, Krikav, Olafeson and Floydmcw.
Ack! This post turned into an essay... will try to break things up in the future
