Techs: Corporations -> Steam Power -> Railroad -> Assembly Line
Switched to Corp to increase trade route yield. Should have done this already last round.
Great persons: got another GA.

So, I used the first one for some culture when Baghdad started to revolt. Next turn the smoke had gone...
Cities: After I got railroad I established mining inc.

in Medina with the GE that I got a while ago. Medina will become my Wallstreet city. It has the Hindu shrine, a bank and now the Mining Inc HQ. I am still contemplating which city would be the best for Ironworks...
Due to my fear that I would not be able to build Wallstreet asap after getting corporations, I built banks in a number of cities - not all of them were actually suitable for making money. Probably, I should have been a bit more patient. Now, I want to get a forge in Medina first (for faster production). So it will be some time before I can start building Wallstreet there. Workers are now building railroads - first on all mines to increase output, then between cities to connect them.
I am trying to get my cities in shape for better research and quickly producing more advanced units - once I get assembly line. Cities at the water build docking bays and galleons (will be upgraded later). Land cities are focusing on production, some of the newer ones get some research infrastructure.
I am the fastest growing civ right now: first in land, already second in population.
Other civs: In the beginning of this round I took Santiago and Madrid from Isa. Unfortunately, I couldn't wait to also get my units in position for taking over Barcelona - all in one turn -, because JC approached Madrid with a big SOD. So, I thought, it would be better to take Madrid and leave Barcelona. After that I made peace with Isa, got 80 gold, but no tech (stubborn lady!). I didn't want to get her as a vassal as well, but wanted JC to take her. So - according to my plan - I would attack her asap when DOWing JC in a few turns. However, things went into another direction: The next turn (after I had made peace with her) Isa vassalized to Mansa!!! Mansa DOWed JC instantly. JC then took Barcelona and detroyed Isa. Now, we have a nice war going on between Mansa and JC. I will stay at the side line. My power relation to JC is 0.7 and to Mansa only 0.2!!! Uff! JC is moving tons of units up north through my country. Perhaps, I should build some special railroads especially for him to speed that up...

During the last turns, Mansa's score declined and declined and declined. I almost overtook him.

(I wonder what Mansa is doing...). His espionage is skyrocketing. Three turns ago, I was able to get a glimpse at his demographics. However, he is producing espionage points faster then I do, so I switched to Gilga, because he will probably be my next target.
Oh, btw: Mansa built the Pentagon, the Broadway and Cristo Redentor during this round.
Here is an overview:
