I've been wondering recently why Civ5 doesn't have some kind of form of a Non-Aggression Treaty, that Civs could sign to prevent constant wars or backstabbing. We don't know too much about any potential new treaty options in the expansion, so I thought I'd bring up the idea. It could be enforced like a peace treaty, completely negating the ability to attack a neighbor's units during the time period of the treaty. The treaties would have various benefits. Peaceful players could potentially protect themselves from wars, shore up friendships with Civs, and use the offer of a treaty to fish out aggressive and/or backstabby Civs. And unlike a Declaration of Friendship, the treaty would actually have some teeth. It would also be nice if we get some control over the length of treaties at some point. What are your thoughts? Is this just a crazy idea? Would you ever sign a Non-Aggression Treaty with another Civ? Could this be useful in multiplayer to form trustworthy alliances?
