That is a good and fair point; but at least they went back and applied the science to it on some of the stuff and YEA on some of the stuff THEY DID write the science to it WHEN THEY DESIGNED IT (like some of the fighters and tech); There is a blueprint book that is a reprinting OF THE ORIGINAL design work for some of the ships; THE UNSIGNED EDITIONS cost 700 USD due to limited reprint run; the signed versions sold retail for 1200 USD + Some of the ORIGINAL artist concepts had plenty of pieces of the tech explained.
