I am playing a game as Aztecs, and entered a defense pact with the AI Russia. I founda few things that weren't documented, I don't think, and found them to be pretty cool.
1) If you capture a enemy city which used to be your allies, you can revert control of it to the ally.
2) If you enter a war with an enemy, and drag along your allies, you are penalized in diplomacy against the enemy (not like we care, since we are bent on wiping them out anyway)
I think you have rebasing rights at their cities too, but that's not news really.
Anyway more cool stuff about civ, i feel that i learn something new about the game design every time i start up a new game.
