Only Hammurabi hasn't refrigeration, but won't trade assembly line for it with me. Oh well, binary research time.
Doing a check of my cities, I see little point in building banks, Markets as very little

is coming through to be multiplied, and if not making 60+ science at moment, I doubt a science multiplier will be built in time, or it has the

to warrant a Laboratory. I whip a Supermarket and any others to remove unhappy citizens.
Workers are on auto build of trade network, or building railway lines all over.
*Starts singing I've been working on the railroad..all the long long day...
Mansa Masu comes on by next turn proposing a trade for assembly line, I make an alteration for Radio, as its on my computers beeline (I'm going to miss the Internet, as Hammurabi already has computers) and its a space ship tech, and the AI is supposedly hard wired not to trade it away.
I hold off on trading with Hatshepsut for Assembly line, as I'll probably gain Industrialization for the same tech, and if I don't well too bad.
Seems Hatties just gotten Industrialization, as she's cancelled our Ivory deal for 18 gold.Looks like I can trade Superconductors for that in 6 turns
I do a triple civics switch into; Nationhood, caste system and free religion. This should get rid of the heathen religion modifier, but I'll lose the favourate civ bonus with Hammurabi, but should stay at pleased.
4 turns to go on Assembly line, then its Factories, and research Plastics as I should be able to trade for Industrialization with hatty. George just received Radio as well, as before he'd trade Medicine for it, and I've just gotten a great merchant, to use on Sids Sushi, or a golden age might be better. The great Scientist I'm holding over, can go on Standard Ethanol or golden age No 2. Hatty also tried on a diplomatic victory, but was a draw with Mansa Masu, split about 350 each, with Pacal, Hammurabi and myself abstaining.
Pacal comes on by, asking for a deal involving Superconductors, I change it to Radio and we get this
Seems my Grand Plan to trade for Industrialization had fallen in a heap, Elizabeth, Hammurabi and Hatty, who are the only 3 to have it, won't trade me for it. I save up 1500 gold, to allow for the free market inflation event, if I get it, and deficit research at 100%.
I've just had a brilliant idea, since we're in Environmentalism, which was voted in by the U.N., I'll spread Sids Sushi all over the AI's, and base it in my wall street city. 2 this end I need to build 2 more banks, and wall street, I'll also spread Standard Ethanol about, if I get to found that as well, as I have a Great Scientist. Maybe Cereal mills would be better, don't want to give away a cultural win to Lizzie do I.
I can't spread both Standard Ethanol and the 2 food corps, as they both interfere with each other
rice, so I resolve to spread Sids Sushi, as that has the highest cost/branch, at 6 gold for me with my meager resources, and for the AI's, it'll be
BANKRUPTING
They can't go into State Property, Mercantilism, or Free Market, to off set costs.
To this end I queue, up the 2 remaining banks, I can build wall street in Capital city, the founding city of Sids Sushi. I'll build executives and start spamming it about the world.
Hammurabi's come on by, asking for a gift of Superconductors, I refused, he went to Cautious, so I changed to Bureaucracy immediately. I'll stay there now, as if they bring up an Emancipation vote, I'll vote yes, and not Deny it, that'll get rid of the Emancipation unhappy, and the the World considers you a Villain unhappy -9 in some cities. Hammurabi's gone back to pleased again, with only -2 'you refused to help us'.
Success, I get an Emancipation vote soon after, and vote

, This results in ALL my cities becoming happy, and some are now growing like weeds. I have to Workshop some farms to stop/curtail growth. I also trade Pacal crab for Dye, as he did not have access to Clam, Crab, Rice or fish, can't have that can I.
All cities are building factories, then coal plants, as I've received and accepted the +4

event for the coal mines, Production is POWER!!!
1812 AD I get the Hostile take over event for Sids Sushi, take over 1 rice

, it ain't happening.
Mansa Masu, the founder of Mining Corporation, comes on by asking for a trade for my gold. I change it to a trade for my excess crabs

, just you wait till I give you Sids Sushi Mansa. I got Hit movies in return.
Elizabeth had just founded Creative Construction in york, looks like only Sids Sushi will be spread about, as Civilized Jewelers competes with Mining corp, and standard Ethanol does with Sids Sushi.
Corporations and how they work, and Analysis
It has started, Sids Sushi, has just spread into London, I didn't do it

My 100% gold rate is falling from -54 at 100% to now 24

at 100% , and
ELIZABETH IS FRIENDLY AS WELL Hammurabi's had enough on his hands for a while now, he's probably looking to have a go at Hatshepsut, no defense pacts for her, just more Sids Sushi rep's.
I'm now building wall street in Capital city to take full advantage of this, if the AI's won't spread it to all cities, I will. Strangely as well, Elizabeth, had the acceptance of a transport grayed out, saying she wouldn't accept it, I accidentally moused over it, and noticed that fact. The last 2 are going to Hammurabi's lands now, so All AI's have had at least 2 reps of Sids Sushi spread to their lands.
