One thing about GalCiv2 that I have wondered about is the scaling of the armaments with respect to hull size. In GalCiv2, any hull size can hold any weapon. A tiny hull can hold the same laser that a huge hull can. It's odd to me that the weapons don't scale in damage like they do with size.
For instance, one cannot mount the 16" guns of the USS Missouri on the USS Cole no matter how you slice it. It would stand to reason that the missiles an SD carries will be both larger and more powerful than the missiles carried by a DD as well as more numerous.
It would be nice if the game could be modded to allow for damage to scale along with size.
