Although the sci-fi backstories of the different vehicles were complete fluff and the notes on sketching and designing were only mildly interesting, the actual final renderings are breathtakingly beautiful.

Granted, the quality is not the same as in the actual book, but the ability to see them from time to time far outweighs that con.
