Update
My galley won. No more barbarian ships appeared.
Traded Alphabet for Math, Iron Working, and some cheaper stuff. The latter is not good for WFYABTA, but with Mansa onboard I am more worried about falling behind in tech than running out of techtrade partners.
Shortly after that I had my first GS. With Philo still far on the tech tree I considered Academy or settling. I was on the way to build two more cities and completely block Roosevelt, that meant low science slider, bad for academy. GS was settled.
My fourth city was founded north, next to Boston, and got me Iron and marble. The fifth went to the southern coastline (more horses, marble, and sheep there), completing Roosevelt's seal off. Granted, the seal was more a "psychological" barrier to Roosevelt than an actual barrier as we had Open Borders, but the Americans never tried to cross it.
I adopted Organized religion. Eventually Mansa built the Apostolitic Palace, which wass good for the time: diplo bonuses and hammer bonuses on my cheap hindu temples and other hindu buildings.
The diplomatic situation was very good, everybody loved me, until two strangely colored workboats came from the north:
Ceaser and
Boudica, two of the four most infamous CIV villains!
Anyway, villains have their uses too. They weren't weak, in fact Boudica's score was second only to Mansa's, but they lacked some of the techs I had. So, I presented them with gifts and signed Open Borders. Both of them already had "We've got too much on our hands", they were not after me...but after whom? Could Boudica be my Mansabreaker?
So do I, sweetheart!
Aesthetics and Drama followed, and the hippodrume enabled some crazy whipping. I believe at the end I was getting +57 turns of unhappiness in some cities. Whatever. Hippodrume and lots of imported happiness resources resulted in me not bothering to police most of my cities.
Part of the whipped was a Swordsmen army. They captured the barbarian cities, I kept Numidian and demolished the other to rebuild it in a better site. Then, the Swordsmen proceeeded to Greenland.
