1580AD(0) We currently control 52% of the world and need 64% for domination. Our power is twice higher than Washington's and will keep growing exponentially, because we are about to discover Steel(Canons) and shut down research to upgrade all old units.
We can probably get the remaining 12% just by conquering Washington, but we need to prevent Boston from flipping to HC. We can do this by either piling tons of units into the city, or using a Great Artist. The city currently has 8.62% chance of revolt, so we'll need at least 10 units in there. This makes a Great Artist much more appealing. The next GP will come either from Arbela in 14 turns (54% Great Artist, 46% Great Engineer), or from Kyoto in 15 turns (31% Artist, 63% Merchant, 4% Engineer). Arbela looks like a more guaranteed place from which to generate the GA, so I order a Theatre(3) there to replace Engineer with 2 Artists. I know that it's our main troops factory, but we need that GA much more than we need a couple extra Rifles. For some reason making this change causes Engineer specialist to get replaced with a citizen. I guess the governor read my mind.
IBT: Surprizingly enough, there are no counter-attacks, despite the fact that Washington was protected by a wounded Rifle and a stack of Cats.
1583(1) At Chicago, we bomb away most of city's defenses and will be able to take it next turn.
Peter has a 15 units stack at New York, so we have to take the city now, without spending time to bomb away the rest of defenses. The first sicide Cat gives our Rifles 92% chance, so I attack with a Rifle and it dies. Second Rifle wins at 88%, third one wins at 97%, and Mace cleans up the wounded Longbow giving us 184$, a Worker, and the city that contains Chichen Itza.
Almost all of our cities are fully improved, so I give some Workers Trade Network orders and put the rest to sleep. I also disband 4 workers, because we have well over a dozen of them and there will be nothing for them to do for the rest of the game (game will end before railroads), so they are just costing us upkeep.
Most distant troops are directed to Boston to prevent revolt, while frontline troops are mainly getting into cities to heal. I upgrade one of the Macemen in Washington to Grenadier to aviod having to fight Grens with Rifles.
IBT: We lose a scouting Musket to Cavalry, but there are no further attacks.
1586(2) Battle of Chicago: First suicide Cat dies. Second "suicide" cat wins at 12%, letting Musket and Mace clean up easily. (Last 2 defenders were Pikemen, so Mace had better odds than Musket.
Peter's SoD is heading towards Phyladelphia, which is defended by only 4 units (Gren and 3 LBs). We can't allow Peter to take the city, because that would force us to fight another war to reach domination. So I try to delay his stack by pillaging the road under it.
The game is now a race to capture Washington's last 3 cities, so I am pushing ahead as hard as I can with all available troops. Wounded Rifle dies to wounded Cav, but Elephant finishes the job. New York is left protected by a single Gren upgraded from Mace (there are no enemies in range, while the other units in the area move to Pillage the hill I expect Russian SoD to occupy next turn. The hill had a village, so I had to use 3 units to make sure it will be pillaged in time. All other healthy units, along with all Cats, move towards Phyladelphia, with they will reach in 3 turns.
1589(3) Russian SoD moved diagonally onto a hill, as expected, so I pillage another roads to delay them even further. Meanwhile, more and more units are heading towards Philadelphia.
HC's borders have expanded far into former American territory, so I am no longer certain that capturing the rest of America will be enough to trigger domination. However, I am still building units, so we shouldn't have problems either way.
1592(4) Persepolis Rifle->Temple to put more cultural pressure along our borders. Arbela hires 2 Artists and chances of GA are up to 55%.
We have trained a Settler, but there is no place to settle him, because all our lands are already covered by our borders, so I put him to sleep on a hill sout of Arbela.
1595(5) Philadelphia's defences are reduced to 0, while some units shuffle around it, prepairing to move on as soon as the city falls.
I put 10% on the culture slider partially to remove unhappiness in a couple cities, and partially to give our new American cities more happy specialists for border expansions when they come out of anarchy.
1598(6) We discover Steel and can buy following technologies: Divine Right, Liberalism, Constitution, and Economics from Peter or HC, and Scientific Method from HC. Out of those techs, Constitution and Economics are the only ones that might matter before the game is over, because they will enable research of Corporation. Divine Right is useless, and Liberalism wouldn't be very apropriate for Mongol Hordes.
Peter is willing to not only stop war with Washington, but also give us Economics, map, and 80$ in return for Steel. In a solo game I'd have fun trying to outrace Peter's SoD to America's final cities, but this is an SG, so I play it safe and take the deal.
Next I sell Steel to HC for Constitution, map, and 180$, and start researching Corporation(7). Both Peter and HC already have it, but this doesn't matter, because the game will be over withing a couple turnsets anyway.
The attack on Philadelphia proceeds as expected, with a single suicide Cat clearing the way for Rifles to attack at 90+ percent odds.
1601(7) Seattle is guarded by 2 LBs and a Pike, so I attack with a small stack without waiting for reinforcements and ignoring 20% defense. A single suicide Cat allows Rifles to attack at 95+ percent odds and easily capture the city. Meanwhile, a massive SoD is moving towards Uzbek and Boston finally has enough troops in it to remove all chance of revolt.
1604(8) Massive stacks approach last American city.
IBT: Washington counter-attacks for the first time in a while, killing one of wounded Rifles in Seattle with a Gren.
1607(9) Unfortunately for Washington, whose 2 Grens are still guarding useless mines, his last city is defended by Longbow, Musket, and Pike. I have so many units nearby that outcome of the battle wouldn't be very different even if Washington did withdraw those Grens into city when he had a chance. 3 Cats decrease defences from 60 to 33%, 2 more suicide without even scratching the CG2 Musket, so I use the other 3 to bombard and attack with a Rifle which also dies, but causes enough damage to enable the next 3 Rifles to destroy all defenders, wiping out American Civilization.
1610(10) We get a GP and it is... A Great Engineer from London. I completely forgot about that city's wonders and it crept up on me, bypassing Arbela that had only 1 turns until its GP.
In other news, Washington and New York expand their borders and we are now at 61.38% of land area. The game will probably be over in 7 turns, when the last of former American cities comes out of resistance. New York is starving due to nearby Incan culture, so I whip the theatre there. If the last 2 cities coming out of resistance will still leave us a few tiles short, we can turn entire populations of cities like Washington and New York into specialists, getting second border expansions there in just a couple of turns.
I guess Sooooo will have the honor of finishing it up, unless we want to wait for Kylearan.
About the only nit I have this turn is the workers sleeping in former England (tons of work still to be done there!) and the excessive building of windmills. We want mines on those hills! (I usually only build windmills if a city is short on food. If it's got sufficient food, probably better to get the additional shields.) But on the whole, we're running pretty smoothly this time. Even managing to run at 60% science with all our cities and no State Property civic yet, woohoo! 
We had a LOT of injured units there, but managed to finish the job. Going to be some healing taking place at Washington, but Zeviz can handle it.
)
Either sooooo or Kylearan (whoever sees this first) should grab the save and hit "next turn" a bunch of times until we win. I will suggest 1) we should run 100% culture (or as close to it as possible) once Corporation is discovered next turn, and 2) we have a settler fortified south of Arbela which can and should be used to plug any cultural gaps we might have to speed up the finish date.
