Situation Assessment: All of the pieces are in place for a cultural victory. Not a whole lot to do at this point. As Methos pointed out, we currently have 2 GA's lounging around. A recap of where we stand on future GA's:
Mecca - 1800 points - 5 turns - 15% GA
Baghdad - 2000 points - 24 turns - 100% GA
Kufah - 2200 points - 32 turns - 83% GA
Damascus - 2400 points - 56 turns - 100% GA
Kufah - 2600 points - 79 turns - 83% GA
Mecca - 2800 points - 90 turns - 15% GA
The diplomatic standpoint is pretty much unchanged. We are currently trading with everybody. We could probably sell our stone and marble at this point, since we probably won't be building anything with them. Unfortunately, there does not seem to be a whole lot of gpt out there to get full value. We will definitely need to monitor this, though.
It doesn't look like Alex is going to be with us much longer. He is currently fighting a 3 front war and losing. He is down to 4 cities. I'll have to hit him up for some techs before he departs for good.
Mecca is still starving. It has 3 forests in its radius, of which only 2 are being used for the health bonus. Cutting one down will cost us at least 2gpt, and starving off a pop point will lose another 2gpt. If I time it right, I should be able to wait until the last minute to clear the forest and farm the tile.
100 Turns Left!
Turn 0 - 1930AD: I dial up Alex and see if he can spare Scientific Method for a good friend. The SOB declines. Our relations are unchanged.
The only city not building wealth or culture is Anjar. It is currently running a science specialist. I switch that to a citizen specialist and bring the Harbor build down to 15 turns from 29 turns. And since we are running at 100% on the culture slider, those cottages are not doing us any good. I add another citizen to bring it down to 10 turns.
IBT: The Greeks lose another city. The Americans have another Settler on the move up in the icy north.
Turn 1 - 1931AD:
Turn 2 - 1932AD:
IBT: Alex wants us to cancel our deals with the Germans.

Meanwhile, Bizmark starts a golden age.
Turn 3 - 1933AD: Since a German Destroyer is now parked off the coast of one of Alex's cities, I decide to ask for SM, again. Still no deal.
Turn 4 - 1934AD: Our expenses just went up by 3gpt. I couldn't figure out why until I noticed that Anjar just grew. I turn on the
Avoid Growth button in both Anjar and Najran, the only 2 cities that are not stagnant.
IBT: Alexander loses another city. Unfortunately, he was selling us pigs from that city. But, since we had sold all of our Deer, it is a wash health-wise.
Turn 5 - 1935AD:

A Great Artist is born in Mecca! Against all odds, we get a Great Artist! In another 19 turns, we will get our 4
th Great Artist out of Baghdad.
Turn 6 - 1936AD: Steel comes in. I start on Scientific Method, next. It will
only take 93 turns. I try once again to see if Alex will part with the tech. The SOB still refuses.
I decide to sell our stone and marble. I really don't see that we need them anymore, but if anyone disagrees the deals can be cancelled after 10 turns.
Qin gives us 12gpt for our stone ...
while George is willing to part with 10gpt for our marble.
We are now positive cash flow at +16gpt with 100% on the culture slider. We will lose 5gpt when Alex finally gets killed off, as we are currently selling him some fish.
Turn 7 - 1937AD: Inflation just ticked up by 2gpt.
IBT: Tokugawa adopts Free Speech and Free Religion. Unfortunately, he is still Annoyed with us.
Turn 8 - 1938AD: Mecca is down to 1 food in its food storage box. I swap one of our forest tiles to a farm. The city is now stagnant. I sent the hammers from the forest chop into a Cannon.
Athens, BTW, probably will not be in Greek hands for much longer ...
Turn 9 - 1939AD: Mecca builds our one and only Cannon and resumes its wealth build.
IBT: The Americans capture Athens. Alex is down to his last city. Meanwhile, Bizmark makes peace with Alex.
Turn 10 - 1940AD: Anjar completes its Harbor and starts building Wealth. The 2 citizen specialists get changed back to science specialists and I add a 3
rd.
90 Turns Left!
Our culture picture after 10 turns:
From what I can tell, the unplanned GA out of Mecca did not change the cultural timeline. Somebody may want to check my math on that point.
