From what I can gather this is the first foray into BBF for 10 Spot Games. This PDF contains 30 new creatures for BBF. There is a wide variety of creatures inside, mostly new and not part of the standard monsters almanac of fantasy creatures. Each has a simple, hand drawn silhouette illustration. The writing is a bit rough and I had hoped for some more background for the creatures. The PDF could also use another editing pass. Still, at 1,39 USD I can`t complain too much of course. It is definitely useful if you need more monsters, especially since the Barebones Bestiary is continually delayed.
