SpaceSector.com had an interview with Galactic Civilizations III Lead Designer Paul Boyer about Beta 2, and touches on some of the new features.
"SS: So, diplomacy will be available on Early Access in Beta 2. What would you say is special and different about diplomacy in GalCiv3 from other 4X games?
Paul Boyer: I think what makes GC3 special, when it comes to diplomacy, is the same thing that makes it special over all: the scope. Not only are there more things to trade, more treaties to make, and more alliances to be formed, there are more ways to do it.
In GC3 when we talk about diplomacy we really include several things; Classic Diplomatic Trade, Techs, and Resources. There is also, Interaction – how different AI characters will treat you and each other, making sure your actions not only affect your relations but their mode. "
