I think people will end up building practical, light, cheap to build and functional ships (to begin with anyway) as ships like a star destroyer whilst would look spectacular and be quite functional in a stand and fight capital ship will be well beyond even the major companies to start off with, therefore I will be going for ships more like the minmatar ships in EVE.....

Cheap, simple and easy to produce and replace, am looking forward to playing around with some designs and seeing what awesome idea's people come up with
