One of the things that I would like to see is the ability to design your own ships. In many great games(Gal Civ 2) players were able to customize or build in game ships. This easy to use interactive window allowed everybody who wasn't in to modding the code of the ships. I think that this would be a great addition to an already amazing game. You could include the shipyard feature as an extra program since this is a rts game.
Anyone else like the idea?
