The fact that the pillage trade isn't available has nearly killed this game for me.
I tried to give you a hint before, but I think I was too indirect with my question:
Do you have some town next to 2 luxury sources in corrupt territory that Persia does not have?
Sometimes in order to get, you must give first!
Here's something I did from another thread:
To get Persia to declare on me, I plan on gifting them my Dye sources.
Original source
I know I gifted cities in some other situations to get AIs to declare on me in that game.
The first person to use gpt for luxuries followed by pillaging (not around his capital, but the trade route still got pillaged) in the hall of fame was Gyathaar in a standard Sid
diplomatic game. He ended up trading with Greece heavily I think. How did he trade with Greece? See the light green area in the middle of the purple area below?
No, he did not have Mauch Chunk captured by Greece. He
gave Greece that city which had two luxury sources. Then he traded for the luxury source, other stuff, and pillaged.
In another
game I played last summer I gifted Persia a city which I intentionally planted next to silks. I didn't know that I would give them the city when I founded that city. But, I planted the city just in case it seemed useful enough to get other things from them. I do remember that Persia had some technology when I gave them that city.
In the 10 AD save it says I'm getting deals of 105 gpt, 47 gpt, an RoP for nothing, 13 gpt, 1 gpt, 20 gpt, 96 gpt, 2 gpt, 1 gpt all from from Persia, and paying 13 gpt to Persia for those silks.
I remembered I had seen evidence of having given at least one city away by Drazek in his 93,000+ game. In the 10 AD save I observe he's importing dyes from Babylon from a city that he gave to them. He also gave another source of dyes to The Hittites:
Drazek's 90k+ game also has a city name "Wines" which Korea owns in the 10 AD save. And he's importing wines from Korea while getting gpt from them also. Maybe he learned a good amount of technology in his games, because in part of those gifted cities also.
