BC's:
Started with SIP, worker first. Tons of production decent food, bad commerce. Built settler on 2 pop, but CDG still beat me to the spot where he built Orleans. I built Prague next to it, and fortunately he didn't have mysticism until the late BCs (when I traded it to him) so Prague got the corn uncontested. Third and fourth cities were in the north, grabbing the deer, beaver and sheep. Built stonehenge and the mids the capital, while pumping workers in other cities. Got GE, and GP, settled both for +6

from rep. Settled GP farm on the sheep, though it was so production poor I think I only got 2-3 GP's from it throughout the game.
You can see my continent is a Buddhist lovefest (founded by Justinian). Mehmed+SB are Hindu, and Sury is Jewish.
50AD:
Since the start was production rich, but commerce poor, I knew I had to DOW on someone. Since CDG was closest, and seemed to have lots of land, I decided to DOW him before construction, but still somewhat late. Perhaps Justinian would have been a better choice, but I was afraid of him bribing Wang in.
800AD:
Second war with CDG. He got feudalism but I got construction and Paris. It had the GLH and the Parthenon, nice.
To 1390AD:
Won Liberalism by 1 turn around 1100-1200 and took chemistry since others already had Nationalism. Wang was nice enough to tech both Economics and Steam Power after he had Philo/Edu before going for Lib. What a nice guy. Then self-teched steel and prepared for a canon/musket/maceman war to finish off CDG. CDG was at war with Mehmed, so I dog-piled and took Lyons, throwing swordsmen at xbows. Made peace when his mace/xbow stack was about to destroy my sword/axe stack.
To 1812:
Before I could start my war on CDG, Wang peace vassaled to me. I made a bunch of trades with him immediately, millitary science + x vs steel + y. On the turn that my peace treaty ended with CDG (1400's) he peace vassaled to Justinian. Since I could see Justinian just had muskets and longbows in his city, whereas I had grenadiers, I decided to DOW anyways. They bribed Mehmed in, who was actually annoying by launching amphibious assaults, and forcing me to retake cities.
Eventually wiped CDG out, and wiped Justinian off the continent (he had 8+ cities on the islands since he went for Astro early), then let him cap. Traded for astro from him. Then took Mehmed's city on my continent, and he cap'd as soon as I landed troops on his mainland (didn't have to take an other city). Then I cap'd Siting Bull after taking one of his cities and killing his stack.
During this time I'm tech brokering between my vassals, as my

and

is pretty bad for the date. I'm also asking them not to trade with Sury. I'm preparing to attack Sury with inf/arty since SB already had rifling when I fought him, so I expected Sury to have infantry, at least. By the time I have a decent inf/art/canon force, Sury doesn't have rifling, but it takes me a while to build enough galleons/frigates. I DOW on him in the 1700's, take his cities on the small island, and start taking his cities on the big island, and eventually take his hollywood city on his home continent, some 6 cities in total.
Sury researched railroad in about 7 turns after I dow'd, but he had 1 machine gun per city max, and artillery>machine guns. Then it was taking him 8 turns to research assembly line (an other immortal player posted that Sury got AL in 5 turns in his game), which he didn't finish before the game ended. He was teching electricity, mass media, and built the UN. I won the vote in 1812.
Also, a final screen shot to show the power of workshops + caste system + state property + biology + chemistry + factories + coal plants:
Map:
This is my second immortal win. IMO it was easier than most maps since Justinian and Wong were so small, they didn't really play like immortal AI, and CDG was expanding slowly, so his production wasn't a problem. Meanwhile Sury had no one to trade with, and SB is hard to kill, yet doesn't attack, so those guys were small as well.
