(0) 550AD OK, here goes. I see the possibility to get into the Industrial Age on this turn by trading for Magnetism and then trading that for Theory of Gravity, but Sirian says to hold off on it and I'll heed his advice. We also want to get over 1000g for Wall Street, so trading away all our money and crippling our gpt probably isn't a good idea. Well, let's see what the game has in store for me this time.
(1) 560AD Busy between turns sequence. We have to renew our deal for Indian furs; the cost goes from 25gpt to 32gpt. Not a big deal, and better than having to raise the lux tax, certainly. Monty comes calling for an alliance against France - should I take it?
Not a big turn as far as cities go; I mainly just move workers. The Aztecs now have Economics and will trade it to us for Military Tradition. That sounds like an OK deal to me (no fear of Aztecs attacking us, that's for sure) and since they will surely get the tech soon anyway, we may as well get a semi-useful tech like Economics for it. The value of Military Tradition as a tech is almost nil at this point (only Aztecs and Japanese lack it) so it's not like we gave away a high-priced tech either. I can now also check how much it costs to research techs ourself... Theory of Gravity can come in 9 turns at -3gpt (and that's only 40% science). Not worth it at the moment, but when we finish getting our maketplaces, banks, and universities built it will almost certainly become easier to research than buy. Something to keep in mind. I stay with research off at the moment though; we need to increase our treasury for Wall Street to give any benefit, after all.
(2) 570AD Our deal for wines ends with the Iroquois... and they are down to only 1 wine after losing cities, so they will not trade it to us. Dang, that hurts. Fortunately Persepolis completes its colossuem this turn so I can scroll through our cities and prevent any cities from going into disorder, but we lose WLTKD almost everywhere. And no one else has an extra luxury out there, so we're going to have to be content with 6 luxuries now. That really sucks. Kicking the luxury rate to 10% shaves over 60gpt off our income and does nothing in the corrupt cities anyway, so I'm going to keep it at 0% for now. Persepolis set to build some muskets for the time being, at least until we get into the Industrial Age and can start building factories and the like.
(3) 580AD Big, BIG turn here. Forbidden Palace completes and our saltpeter deals come up for renewal. We also get more than 100gpt income back again as deals end and the effects of the FP are felt. Now I can actually do something in the diplomacy screen. OK, first job is to go through newly uncorrupted cities and rearrange tiles/production. France has razed an Iroquois city that contained a saltpeter resource just beyond our borders, so I change Arbela over to a settler to send it off there next turn. A new city will also take cultural pressure off Arbela - very nice. I will not make the Ergili mistake with location this time.
OK, now for the deals. I check to see who will give us a better price for saltpeter, France or India, and France's is considerably better. So I send saltpeter, WM, and 815g to France for Magnetism. Then Magnetism, silks, WM, and 34gpt to the Iroquois for Theory of Gravity. We enter the Industrial Age and get Nationalism as expected, which now has an unusually high value here in 1.29f. The AI civs do NOT all have Nationalism, so I get to make more deals. Babylon, and Rome are the only ones with it, so we've got a free tech here that we can sell @4th civ price. Nice! India will give us Medicine and Democracy for it, which will put us only 1 tech (Communism) behind the tech leaders Rome and Bablyon. I make the deal (too bad they have 0g and 0gpt; even with getting Medicine for free, we are still not getting full value on the tech). Then I trade Medicine to France and clean out all their gold: 822g in a lump sum payment. That should get us over the 1000 mark! A good round of trading overall, though I have done better. The price for Communism at 3rd civ price is outrageous (not that we want it anyway), and I think it may be more productive now to research than buy. So I'm going to take the unorthodox step of turning ON research here to go after Sanitation (15 turns, +40gpt). With both Steam Power, Industrialization, and Espionage undiscovered, the AI will almost certainly not get Sanitation before us and we will then have a tech that we can sell @2nd civ price for any new techs discovered. An interesting plan, and we'll see if it works or if I get the
applied afterwards.
(4) 590AD France completes Smith's, so the cascade is kaput. Shakespeare could screw things up, but for the moment there is no work on wonders anywhere. A quiet turn after the massive dealings I did last turn. France is also gracious with us now, by the way.
(5) 600AD When checking the diplomacy active deals, I notice that we are paying some 15gpt and silks to maintain a ROP with Bablyon. Huh? I know that's the remains of a tech deal. Instead, we sell our silks to Hammy for 15gpt and ditch the ROP. He stays polite with us. The increase in income allows us to bump the science rate up a notch; Sanitation due in 10turns at +12gpt.
(6) 610AD Free Artistry must have just been discovered, because the Babylonians and Romans start work on Shakespeare's. This could pose a problem... We build our first rifle in Persepolis and order up another. This reminds me that we can now draft (silly me) and we institute it in a few cities. Not too many (because we are only pulling +10gpt until we get Wall Street), but here are the cities: Bactra, Sidon, Hamadan, Antioch. A lot of good sites for drafting either did not have the necessary population or were too close to being unhappy as it was. When marketplaces finish soon, it should be possible to draft in other cities. I also rarely use the draft and am not too familiar with it, so perhaps these were not the best locations. I'm sure Sirian will tell me if they were not!
(7) 620AD The French and Indians also start Shakespeare. Since no one has discovered Stem Power yet, we may - may - be safe here. Another possibility is to have Pasargadae build Shakespeare's to break the cascade. Or let me rephrase that - Babylon and Rome now have Steam Power this turn. I'll probably hold off on Wall Street to let the team decide if we want to switch Pasargadae to Shakeapeare's and break the cascade.
(8) 630AD A TON of stuff completes this turn, mostly marketplaces and banks. Our income goes up almost 35gpt as a result! I put many on universities, because they are cheap, provide more culture, and we are doing research now. Kandahar founded to the east of Arbela; it IS in an Ergili position, but due to the location of the coastline there was nothing I could do about it. The Indian city it is next to has NOT expanded its cultural borders yet, so we have a good shot to control the 3 tiles over which they would be fighting. And when our borders expand, we will claim another saltpeter resource.
(9) 640AD Library rushed in Kandahar (of course). Pasargadae can build Wall Street next turn, but I am going to hold off and see what the team says regarding Shakeapeare. At worst, we lose the production from 1 turn, so no biggie.
(10) 650AD Nothing important happened on this turn. Sanitation due in 5 turns at +70gpt (can go to 4 turns at +7gpt). We will also get an extra saltpeter in 3 turns at Kandahar, which can be traded to India for a decent sum of money. The question really concerns what to do with Pasargadae. It has 299 shields at the moment; Wall Street costs 300 and Shakespeare costs 400. We can almost certainly get the wonder, but Inudstrialization may be discovered in the 4 turns it will take to build it, and thus we would achieve nothing. It's a judgement call for the group, and keep in mind that it will cost us roughly 1000g to buy Free Artistry. My gut feeling is that we should ignore Shakespeare and hope for the best, but I don't want to make an arbitary decision like that myself. Others?
RBE1 650AD
Without the marketplace, I couldn't have gotten it higher than 4 shields/turn, and consequently 50 turns to build the FP. I think we can all agree that the 350g for a marketplace rush is worth a FP up 17 turns earlier, right? 
Ah well, my bad. Probably "only" cost us a few hundred gold, a few dozens shields, and ~1% of our southern growth curve, give or take. I did think about corruption, but each new city coreward on a large map takes less of a toll than smaller maps, and I rolled craps on this one.
