^ I can't decide if I like no tech trading or not
On the one hand it takes away a lot of the intrigue and diplo options. On the other hand it's kinda nice to always know if you're in the lead or not as all the AIs move through the same tech sequence together.
Other thoughts so far from playing a couple hundred turns of Rome, Inca, Khmer, Russia, Native America (not finished any yet!)
Most civs have room for a good 10 cities peacefully which makes cheap organized courthouses good. Imperialistic/creative for Russia was also good, but I just didn't get on so well with the blandness of their land. I'm surprised Russia is considered the strongest and Rome only 4th strongest.
After my initial thought that it was OK the Khmer start bogs down from all the jungle, and I agree it's a tough one.
I'm also surprised that Native America was deemed the hardest. Monty makes things a bit awkward but he's manageable and there is a ridiculous amount of great land and resources. Isolation isn't a problem like normal (no tech trading), and since Europe is accessible pre-optics you have great early overseas trade routes.
Inca I can't make up my mind about. Sad to say I think rushing Pacal is probably the best idea.
Next I'm going to try China and build some wonders
