First thing I have to say is that this book is nothing like RE: Monster, a manga written by someone else. The only similarity is the guy becomes a goblin and leads his people. Woohoo.
Now seriously, this book is very well written. Unlike most people I enjoy the minutia of the game mechanics. If you do not then this may not be for you. For the performance, Jeff Hayes delivers as always and keeps you engaged. Very well done. I will recommend.
