Bloodclot
Chieftain
I'm playing an interesting Civ3 game right now. The Japanese and Chinese are to my south. I didn't have rubber but there was a source within the radius of a Japanese city (size 11 I think) that was near three of my cities that are like size 16/17. Anyway, the Chinese declared war on the Japanese and the Chinese fought to capture that particular city. They were successful, but after they captured it, the city was reduced to size 10 and the Radius decreased. Its decrease allowed my culture to overcome the square that had the rubber in it and now I have that resource! I almost fell off my chair when that happened!
