A couple things I wanted to know, however.  I've started up GalCiv I again and noticed that, at the beginning of the game, civilizations grow immensely fast.  It seems like in the beginning all I can do is build colony ships to keep up.  This is kind of annoying.  Shouldn't colonization go a little bit more slowly to give the game a more epic feel?
Also, is there a way to stop other civilizations from trespassing through your space?  Is there some kind of border agreement now?
Finally - and this is the most minor of things - are the numbers reworked to show that I have 1.2 trillion citizens instead of 1200 billion?  What about soldiers?  Do I lose 2 billion instead of 2000 million?
