Victory!
Thanks for the tips, NitroJay. Unfortunately, I haven't visited the thread since my last post, so I didn't get to use any of them, but a lot of 'em ended up being part of my winning strategy.
I had it all down, and finally got the 5 religions, when I went for the population size. That ended up being impossible with how big China got, so I decided to use the China harass I used previously when I was gunning for Confucianism. 1 warrior holds out China 'til around turn 65 when they finally get Mathematics & catapults, but 2 warriors can keep China bottled in the entire game. Look at these two beautiful, stick wielding bald warriors:
That's 1200 AD. They only allowed 3 cities to be built in China. I had to pull them back when China first got catapults, but they kept the second city from being built for a long time. One also got me China's worker early in the game, so I could get marble hooked up before my second city was even built, and later they got me a few extra workers when I started to expand after killing the elephants. I officially dedicate my victory to those two, and there will be massive parades in Delhi, yes... Delhi, the starting location city... when they return.
Here's the victory shot:
Persia ended up being a great ally. Sure, during my one game (when I tried the 1 warrior harass in China) they gave me the plague, but in my winning game not only did they trade me Monarchy & Calendar, but they captured the city north of them before getting The Great Wall. I have no idea what happened to the barbarians after that, oddly enough. China, maybe? Still, it was almost 900 AD when they got it, so it wasn't so much a game changer as a nice relief.
Last 300 years were such a breeze, despite a miserly 20% tech rate, that I ended up with the Apostolic Palace and ruling a vast Buddhist empire from Persia to Japan. Got the Parthenon in Delhi as well, mostly out of lack of anything else to build.
Now, off to China...
