I just played up to 1400AD. I don't have time for a full report atm, but I'll outline the most notable developments in the BC era for now.
The Americans were clever enough to realize they needed fishing and agriculture as starting techs, which was helpful. I started by building a fleet of work boats for all that seafood out there, while in the meantime I teched to bronze working to chop the Moai Statues, which were built in 2260BC.
Next I picked up writing, and assigned two scientists. Meanwhile, the two additional warriors I had built at some point when I had nothing else to do got the exciting job to go fogbusting in the ice desert for the next 2000 years.
In 1490BC my mighty army of 3 warriors was actually the eighth best military power out of eleven.
My next two priorities were CoL for religion and caste system, and metal casting for the Colossus. As both take long to research, I decided to go for the Oracle, despite it being rather late and not even having researched mysticm yet. But I needed priesthood anyway for CoL so I took the risk. And see there... !
I grabbed metal casting and continued to reseach CoL. Maybe I should have gone for monarchy first, as I already three unhappy citizens, but I didn't want to lose confucianism. So i took the religion and went for monarchy afterwards, when only a few rounds later the American islanders once again demonstrated their keen sense of art and craftmanship:
And a few centuries later:
So up till then the game had progressed in excellent fashion, with America getting several crucial wonders, a religion, and profiting from six or seven scientists in Washington with caste system and the GL. Research was good, Production was good and new great scientists were being pumped out like mad. I even got a free military instructor thanks to a random event. But will it be enough to compete against the whole world? On a huge map?
I'll let you know tomorrow after work.
For those who can't wait, I attached the save from 1400AD. It's the period when things are starting to get interesting!
