@Jersey Joe: Yeah, 1000 culture each. Getting any of them (or Tyre) to 10k would require sacrificing some Great Artists -- I'd rather commit those to military pushes.
New cities are limited to 34 by my count:
Auto-built: Theater, Islamic Community, Hebrew Community, Stonehead (1 each)
Build Temple 1
Academy 2
Colosseum 2
Observatory 1 = 10
Courthouse 1
Library 2
Synagogue 1
Opera 3
Egypt Flag 1
War Memorial 1
Telegraph 1 = 20
Barracks 1
Police HQ 1
Religious Center 1
University 4
Great Religious Center 3 = 30
Mission 1
Great Synagogue 3 = 34
And it'll take 7 turns to hit 20 culture/turn:
Academy 6
University 10
Opera 13
Library 15
Temple 16
Religious Center 17
Great Religious Ctr 20
It's probably not worth chasing that 34 culture figure, though. Two expansions per new city will help us a ton everywhere except the giant deserts.
Here's how the culture growth breaks down:
0 +4
4 +6
10 +10
20 +13
33 +15
48 +16
64 +17
81 +20
101 +20
... 1000 reached after 30-45 more turns (depending on how much more culture we rush).
Hmm, for the next target: How about annexing Maghreb ASAP and building our shipping there? It will take a ship 3 turns to make the crossing vs. 5 turns due W of Teoti.
I note our military is a bit weak: Only 33 Hotchkisses in the save I checked. We should spend some MM on improving marginal cities like Persepolis (at size 21 can build 1-turn Hotchkisses with 1 Policeman) and Hieraconpolis (1-turn HKs with 5 Policemen -- build a Telegraph there).
Tyre could use more watered/railed desert to quick grow, then build some mines.
Arbela could get rails and mines (size 22 already!).
Sidon could get 2-turn growth by watering+railing the desert tiles. Lots of shields
A few other promising cities
Pasargadae - growth
Teheran - growth
Vladivostok - growth
Tzint - growth (water the desert tiles)
Avaris - growth (water the desert tiles to speed growth to 20, then dig mines)
Tangier - growth ( lots of hills)
Lisht - growing fast, needs mined hills.
Maybe St. Petersburg, Smolesnk, Krasnoyarsk, Rostov, Bryansk.
Probably a few cities in Old USA.
