I fear the AI's are dominating the world. Way behind (as usual)

Had a city in Mexico (was a good location to block Carthage I thought) , which was bought by Carthage, we bought it back and they bought it right back.
Also lost another city in South America to a Knight

Attacked in Asia, conquered Mongols mostly with spies, Power went to Supreme around 1875
Carthagians are mostly in Democracy and are rich when not, so hard to buy cities
Conquered Spain 1907
Vikings 1917
Carthage 19xx
technique was spies take out city walls in capital
take capital unil $ < 1000
buy rest of cities when no capital left
final population 43,570,000
56 techs, was just about to get Automobile, so no tanks for me
Stayed in Fundementalism from 1900 on, so score will not be great.
Carthage was last AI and really hadn't scratched them, so it felt like a game of Invasian America with me playing the bad guys. Also from my first set of 4 transports to North America 2 were sunk by the AI, ouch

I must say that by 1800, I thought victory was improbable and if it wasnt a GotM would probably have quit, but it goes to show the AI can be defeated from quite bad positions
