This looks like it could be a useful addition to S&S, but there appear to be a number of editing and/or math problems with the design system. Full-size and 1/2 size H-pods are not described. Sick bays are also not described. I note that in the volume 2 manual, it is implied that starship sick bays include some number of cryo tubes, but this is not stated here. Also, the construction points (CP) needed to build the basic ships in the S&S book is much higher than what would be available under this system. The basic frigate in S&S would cost at least 68.5 CP, but would have a design budget of only 50 CP under this system. Something just doesn't add up.
Also, bookmarks in the pdf would be extremely helpful, as would an editable ship design sheet.
Edited: I felt I should add that the new systems and rules included look good and could add interesting twists to the game.
2nd Edit: I re-read the rules and realized that what I thought was a fundamental flaw in the system was actually just a misunderstanding on my part. Also, the system values have been updated since I bought it, so the math now works better: it's actually possible to build the basic ships with this sytem now. There's still several editing problems, however, and the whole DB/CP/PPB thing is not explained very clearly. I've upped my review since I think this will be useful and has some good ideas, but explanation needs some work.
