Ok, played some 2 new maps, 2 times Oracle at 2500 BC, guess the game wants to tell me I should finish this Writeup ^^ . Here we go:
Last time, you read a very short part of Replay, which was mainly about the last steps of the setup towards the GA.
What you're gonna read now, is: How to use a GA to get to Sushi in the BCs, featuring my Liberalism -> Medicine Slingshot as a first time official!
You still remember the overview I gave to you at 1000 BC, that should be enough to know about the status of the Incan Empire, if you're interessted, download BUFFY and have a look at the savegame.
Here are the years from 770 BC - 30 AD! (This is gonna be a lot of work and a lot to read, but I have some really good Coffey next to me, you should also fetch yourself some ;D .
tl;dl read the bold parts again) .
A GS has been born, and I use him to start the first
golden Age of the Incan Empire. Now I can finally
switch to Buro, but in addition to that, I change from Slavery to
CS and from OR to
Pacifism. This enables the Empire to work
10 Scientist-Specialsts and 1 Engineer in Hamburg in addition to the 2 Scientists the city already got from the GL. With the 100% Bonus to GP-generation from Pacifism, Hamburg jumps to
189 
! Here is a picture of the starving city:
FIN Colossus Coast during a GA looks nice, doesn't it? ;D On the screen, you can also see, that I'm
short before finishing Liberalism. You can also see, that the next GP will arise in only 5 turns! For those of you who don't play Marathon: Length of a GA on Marathon is 16 turns and I get +50% from having the MoM, so that makes 24 turns. Now you'll think "ok, that roughly gives him 3-4 GPs" .
"No" I'm gonna say, "this will give me 5 GPs!" because Hamburg will not be the only GP Farm I'll work!
Bombay has the Colossus, the GLH and the Oracle, that alone makes 6 * 3,5 = 21 :gp ! Why not work some Specialists in addition to that? Now Bombay doesn't have that much

so that it really can, but it is enough for 3 Merchants and again the 1 Engineer enabled by the Forge. This brings the city up to 63

! Here is a picture for you:
But Bombay is not the only city having Wonders, let's have a look at what
Kyoto is doing:
87

! Regrettably the city has a very high chance of creating a GA, but this is not gonna be the only GA I wanna have, I wanna have 4, and for that, I'm gonna need some more GPs, so a GA would be absolutely fine, though not the best I could get.
Now why did I decide for
Merchants and not Scientists: Thing is, that most of the GPs will be coming from Hamburg, and Hamburg is already "polluted" from the GL, so it per se has a chance of creating GSs. I actually only really "need" 1 GS for building an Academy in Cuzco. After that,
it doesn matter! I really did some Math during this round, and the only difference I found between a GS and a GM is, that the GS helps reach Techs sooner, but only if one has enough

to run 100% Research anyway. If one hasn't, the Trademission from the GM will give so much

, that one can again convert to

by setting the Slider to 100%, that it really makes no difference at all
(slight lie: First, one needs a lot of Libraries and Universities for this to be true, otherwise GSs are slightly better, and in addition, generally, the later GSs are better, though then, one has greater use for GMs) !
What I have in front of me is a very very long run for very large Techs, no way I'm gonna keep the Slider at 100% all the time, not even with Failgold (which I cannot even use excessively because I decided that I wanna build Settlers and Universities) , and as a totally different kind of matter: I have also started on military production,
atm. I'm building HAs which I want to upgrade to Cavs, and, one step back: Not long
after the first GA I'm going to trigger the next one, and for that I need 2 different kinds of GPs. Last reason to run GMs in the hybrid-GP-Farms is, that
some techs are simply not "bulbable" with GSs, like Gunpowder, Constitution, Democracy, Economics, Corps...
Now you got all reasons to why to run Merchants in Kyoto and Bombay. Only thing that I wished for at that time was, that I'd have had the Pyramids, those Specialists would have been so many

at that time... Btw.: How much
BPT is the Empire doing?
700! Pretty impressive for the time, ain't it? Don't forget, Cuzco has neither an Academy nor Oxford, we'll watch how this will develop.
One thing I also do during every GA:
Micro all cities to work less
and more
! I don't know if this makes sense tbh, I simply go by Intuition, and that tells me, that if a tile gets a bonus from something, that I'm gonna take it ;D . That doesn't of course mean that I switch from FPs to normal Plains, but I don't work that much Grassland during GAs as a general rule if Plains are available, I also work more Mines then Cottages. Here is a Screen of the Graphs for you, so that you can just see the power of this move:
Production basically doubles with the GA and with microing the tiles. What some of you may also notice, is that I whipped really hard directly before the GA. This in theory isn't really good, as during the GA, one wants to have the largest possible Pop, but there was simply no other way, I had improved so much

that Population was growing onto unimproved tiles, and working unimproved tiles is something I don't do. I experience this in more and more of my games, I'm already whipping hard and stacking anger, and still,
1.5 Workers / city don't do, that's why I tend to disagree with that rule more and more and am even
thinking about building something like 1.75 - 2 Workers / city in the future!
This was all to the GA, now lets get back at what happens:
770 BC, I found the first city on an island, it's named
Arequipa:
I make use of the possibility to work an
Artist in it and produce

for a fast Borderpop.
Same turn I discover the totally underdeveloped Willem, now there is only Lincoln yet to meet.
750 BC: The also underdeveloped
Suleiman vassalizes peacefully to Cyrus. This makes Washington go out of WHEOOHRN again. Cyrus must have really built some Military, good that I'm friendly with him, in contrast to all the other Civs who have joined the big Loveparade of Hinduists he is plotting a war for quite some time now. I wonder whom it is going against, maybe Mansa, the only other Islamist then Sulei?
Same turn I found the 22nd city of the Empire, called
Nasca, again, also on an island:
730 BC, Cyrus liberates his Oversea Colonies,
Saladin enters the round.
Same turn, Berlin has reconquered some

!
The
GT in Berlin is on its way too, takes still some time, 900

are a huge investment, but you'll see how overpowered it is in near time.
720 BC: I discover Galleys of Mansa, Hatty and Sulei entering my territory. They all want to settle those Islands. "Go away, those are my Islands", but screaming doesn't help. I cannot close Borders with them, as relations to Mansa are already bad enough because he's such a religious fanatic and with Hatty I'd loose a good tradepartner.
Same turn, I again conduct some of my
"Trades of Doom" . I just mention this again, as it's a tactic I think not everybody really knows, and it's really simple: Give a tech to someone that he is already researching, get some

for it, and besides that, put some Revolutions to [stupid Civic xy] on the table and let him revolutionize longer than he would have taken to research the tech in full. Then watch him revolutionize back, and again loose some turns.
After those trades,
I decide to switch Specialists from Merchants to Scientists again. I've got some much money right now, that I can run deficit for up to SM, and my new Math concludes, that if I can bulb Bio, GSs are stronger again (I didn't know how the value of the Trademission would develop though, so I'm just guessing again. In fact I think, that the difference is as I said, Scientists are faster if one has enough money, Merchants are more flexible. )
Again in the same turn another
GS is born. He is sent to Cuzco to build an
Academy. 3 turns later, it's ready, and it alone brings in 65

/ turn! The Incan Empire is now doing an amazing of 900+

/ turn!
710 BC is the year of the next foundation of a city, here goes #23 named
Atico.
700 BC: The
AP is built and it's christian!
670 BC: Berlin has reconquered its complete

! The city finds back to its old strength.
660 BC: Another
GS is born in Hamburg. I use him to
bulb part of PP.
Same Turn, I gift 250g to
Viccy for diplomatic bonuses. I need her on
friendly, as she is
researching Optics, and I really want that Circumnavigation bonus. I also start the construction of a Trireme, that I'm going to upgrade into a Caravelle to get it. I was trading Worldmaps every turn, but there is always 1 tile missing for Circumnavigation, I cannot let it happen that someone else gets this on this map, where I want to found over 50 overseas cities.
650 BC, another island-city named
Juli is founded by me. It secures 3 times Seafood, one of the really good locations that I wanted to secure.
I also notice
Cyrus' SoD moving through my territory. I now know, that he's going against Mansa. Have fun Mansa, he's gonna kill you!
Btw.: Atm I'm doing
73 GPT through ressource-trade alone! This is due to me renegotiating every trade whenever there is only 1 GPT more available. Takes some time, but it's necessary for HoF play.
