More precisely, with the Galactic Civilizations II Ship Editor.
The GC2 Ship Editor is about 6 years old now and people are still creating and showing off some really cool ship designs with it. This is awesome, but I can't wait to see what people will come up with the new ship editor in GalCiv 3.
I would sometimes spend more hours designing ships than I actually did playing the game. I've seen lots of talk about the GC ship editor, so I think it's safe to assume you are just as excited as I am about it.
