How's the shipbuilding in the game? Will there be any need to pester Kryo to make another one of his great shipbuilding mods? That was a must have for me in GalCiv2. It was about the only mod I used actually. That and Formis's excellent alien animations.
Actually, since you mention it, there is something in GC3 which is a little bit like KHSM - you can offset various parts on the X Y Z axes, meaning that you don't need to use extender parts to get the look that you want. That right there is a massive improvement.
