Hehe, thanks to everyone for a great gauntlet!
I rarely had more than 1 or 2 workshops/city, so Mercantilism was probably better than State Property. It had a couple of advantages: Early GEs, less pop at same production, much less costs compared to Enviro. All that enabled me to use every single unit for offense (just one marine remained in Delhi), while running high culture - in fact 100% for a lot of turns in the end. This probably was the main reason for my 32k compared to Lexads 28k and Moonsingers 26k.
As for choice of leaders, I still think Gandhi & Asoka are on par. Gandhi can give you very early Pentagon & West Point, and in addition even a 3rd GE in time to be effective. Btw I used only Engineer Specialist all the way, culture slider works perfectly for border expansion.
