Side question, I never used POD services on DTRPG or similar, what kind of print quality do you can expect in those cases? Is it the print shop print and bind quality or something more?
I picked up POD copies for 1st and 2nd Succession Wars for a friend while getting other POD books recently, and did side-by-side comparisons with my copies. The differences are:
Slightly different paper size
slightly lighter ink on the interior pages
updated indicia on the back cover
a couple of blank pages in the back of the book, one of which has print details and a QR code on it.
Unless you knew what to look for, I can't imagine anyone being able to distinguish a POD edition from the original one
