Tech: Agg - AH - Mining - BW - Archery - Wheel - Pottery - Writing
City's Settled: T1, T37, T47, T64. (3960 BC, 2520 BC, 2120 BC, 1440 BC)
T26: I've made 3 warriors and lost my scout to barbs. I've been applying extra worker turns towards a plains river farm while waiting for Mining to finish. This is also the moment I realized I'm isolated, with maybe a chance for a boat to go to another continent on a peninsula tip over westward, but I'm not counting on it.
T45: The 2nd city location seemed obvious. Flood plains + the ability to share the wheat and/or pigs with the capital allows for rapid growth while the capital works the mines to produce more Settlers and Workers. I lost 2 warriors to barbs further influencing my need for Archery after spotting no horses or copper on my continent. 3rd city location was either between the pigs NE or the wheat SW, but grass pigs give +6

and this city can share cottages on the flood plains. The SW wheat is only +4

/+1

, so it's a pretty clear 3rd city location.
T74: The 4th city could've also been the pigs + clam spot just east of the wheat + marble location, but the wheat + marble spot is A) good enough, B) able to share a +4

mine and a grass cottage with the capital, and C) 2 distance shorter in distance maintenance cost.
I have 3 Archers out spawn busting, with a 4th en route. Barbs shouldn't be as much of an issue. If axes start roaming I can whip a few more archers in time.
Maybe my 4th city should've been/5th city could be one which works the silver to the north, connecting it to the empire. This seems sub optimal though.
My main issue here is deciding on my next tech! (Just finished Writing.)
Alphabet will allow Research building and costs 405

.
Math + Currency allows Wealth building and gives an additional trade route to cities (+1

per city atm) and costs 878

.
Fishing may be squeezed in for the Pigs + Clams city, costing 65

.
Masonry will give me the Marble resource, as an improved tile and as a bonus towards wonder building/fail gold, costing 92

.
Masonry would be a reason to also go for Aesthetics + Literature for the Great Library and eventual National Epic, but this costs an additional 674

.
768

spent for the Great Library - which I might not even gain - seems like a large cost, especially after the tiles I've scouted and being in the arid climate meaning I likely won't have a good GP farm to take advantage of National Epic really well. The fail gold from this line is the best benefit.
Meditation + Priesthood + Monarchy allows Hereditary rule for plenty of +

, costing 593

.
Meditation + Priesthood + Code of Laws could introduce Confucianism so that I have a religion, allow Caste System switches so I can abuse cities at high

and

towards

and

instead of flopping around, with nothing good to whip. It also allows me to go towards Civil Service (928

after Math). This CoL line costs 593

. It also unlocks the UU sacrificial altar. Monarchy/CoL could be teched after whichever isn't for 405

.
Ultimately, I want to grab Optics so I can meet other civs. This line requires Fishing + Sailing + Metal Casting + Iron Working + Compass + Machinery + Optics, a total of 3098

.
My thought is to go for Fishing, then the Med + PH + Monarchy route, Hereditary rule will help solve the

crisis, albeit at the extra cost of +1

/t per

from the unit support cost. Also is a slight backup against barb axes/spears. After Monarchy, I think I'd want Math + Currency for Wealth building along with the +1

. Alphabet seems like a better choice in the short run, but since I have a 3100

mountain ahead of me, the +25% from Libraries leads to a higher

:1.25

with

:

ratio than

:

with

:

. This should save roughly 620

and give +1

/city from the trade route, more than making up for the 473

additional cost over Alphabet. From here I'd plan to go straight for Optics. (Fishing + MC + Sailing + IW + Machinery + Compass + Optics)
Maybe going (Fishing), Monarchy, then Math + Currency, then CoL (reducing the cost by 68

due to another prerequisite tech), then Civil Service, then Optics route is better though. Bureaucracy will be a ton of help and this detour costs 860

more. If roughly half of my tech is coming from my capital after the 1st academy and a good number of cottage++, the 3100

mountain is ~1500

teched by the capital, meaning the +50%

boost (and +50%

:

Wealth building) is so helpful that the detour practically pays for itself by the time I hit Optics.
Another question here is where should my 5th city be? Pigs + Clams next to my 4th city, or Crab + Silver to the north for the +

Silver. I think it should be Pigs + Clams, with 6th at the Crab + Silver, remaining coastal but rushing monument while a work boat from the 3rd or 4th city grabs the clams.The more I think about it though, the more I like reversing the order.
