In the stream on Friday Paul talked about building a starport in another civ's territory (11:34 in this video). I know the team is still learning how these mobile starports are going to effect the game, but this seems like a bad idea to me. I think civs should only be able to build starports in their own territory, or maybe only be able to channel production to starports that are in their own zone of control. ZoC needs to mean something, and the idea that someone can sent one constructor into your territory and then suddenly build an entire fleet in your territory feels to me like it violates the idea of a Civ having control over an area. At the very least, building a starport in another civ's territory should be an act of war.
