I've logged more hours than I care to admit on the ship designer in GalCiv II, and enough in GalCiv III to know the similarities/differences. Something that really bothers me is that every time I develop a new technology, I have to go through all my custom ships, trying to remember which uses what, and update them, marking older versions as obsolete. Worse, the next time I play I might take a different approach to research; in one game I may have a hyperwarp drive and photon torpedoes, but in the next I may spend time on armor instead of engines. Thus, the ship I built in my previous game with hyperwarp and photon torpedoes is no longer available because I do not have all the same techs. My options are to do research exactly the same way every game, or to flood my list with a hundred odd ships that are almost identical.
What I would like to see is a generic 'slot' option for each component. Instead of designing a ship with warp drive and stingers, then upgrading it later to hyperwarp and photon torpedos, I'd like to design it with an "Engine" and a "Missile Weapon" on those hardpoints. Each time I develop a new tech in one of these areas, my design "Ship M<n>" becomes "Ship M<n+1>", which has the new technology. This would save me quite a lot of time and headache, without taking away any of my control. Thank you, Stardock, for reading and for making a fantastic game.
