"Is the US Army currently not driving through the Iraqi front lines to target the key cities in the centre of Iraq? The idea that a war MUST be fought from the outer borders inward is sloppy tactical thinking."--Quote by Asharak
I agree with you, but quote above is not sound. What Bimbo15 is saying is not about fighting wars from the outside in, but territorial control. The U.S. couldn't simply park it's army 5 miles outside of Baghdad before the war began and then say, Okay, now we'll attack you. As soon as the U.S. crossed the border the war started. This is what Bimbo15 is talking about. The A.I doesn't have to attack border planets first just because a border exists, but if they cross the border and head for the main planets of the empire then that would mean war in reality.
However, we are dealing in interstellar space and the reality would not be the same as on a planet. In space, each system would be it's own border. Think of the Humans in the Sol system. They also have a colony on Alpha Centauri, which is the nearest star. Space is so big that there is no way the Humans could effectively stop any ships traveling between the 4.3 light years between those stars. Therefore each Solar system would probably have it's own defense perimeter around its outermost planet. As for the space between stars, Humans could monitor it with sensors, but anything more would be a total waste of resources. This is why the game shouldn't have borders, except for within a solar system, and the A.I. already respects this cause they can't colonize another planet in a solar system if you already have a colony in that same system.
