I got culture bombed by Ghandi on a small two city island. He wasn't at war with me, but he didn't like me (Warmonger) as I was in the process of razing a massive out of control Hiawatha AI. The bomb took Uranium and Oil. It made me think twice about being too cavalier with my big destroyer fleet. This was during a Prince or King Archipelago game I think. I'd gave the AI props. Then I remembered that I basically had won the game once I got to 3-4 Destroyers, and was only finishing out to get the achievements... ...although I did take a certain pleasure in blowing up Catherine's belligerent units like shotgun to gopher.
