Years ago I was supporting this project when it was a paid email subscription. I was also able to get in on the Lulu POD of this title. The creatures themselves have not made their way into any of my games. I was looking at a few of them before writing this review and felt that I can quickly adapt any of these creatures to either the newest edition the original RPG or any of the OSR variants since the creatures have enough information and a baseline that you can use to move the dials for your game.
For the product each monster has a full page, color image, and then a full page write up. Formatting wise I would of prefered to if a creature didn't fill a page leaving blank space over starting the write up for the next creature. Sometimes it can get a little distracting having to flip around the full page art.
I feel it is a worthwhile investment for the content if you are looking for something new and exciting for your RPG game. Checking the different sources that the artist Nicholas Cloister was using in the past and including Patreon it appears that he has gone silent. I fear that the RPG community may have lost a creator that had a bright future ahead of them.
I encourage anyone who is looking for something a little different, maybe more aquatic, and that allows for some creative interpertation to pick up this title. At PWYW it is a great deal and will allow you to set your own value.
