To keep it in perspective, this isn't about the quality of the rules themselves, but about the quality of the premium hardcover POD.

I had high expectations of a tabletop RPG book that costs $60+ that is print on demand, yet I was left disappointed to see that the entirely-adhesive spine (there's no other material reinforcing it) has already begun to split upon the first time opening the book. Considering this is the rulebook that will be present at our table during every game night, I'd expect there to be a bit more resilience to it. Since the cost of production is being leveraged heavily onto the customer, I'm disappointed by the low quality the 'premium' option has to offer.
