This product impressed me. I'm not one for systemless products usually, but the preview showed good art, good descriptions and a systemless "system" to scale each beast in accordance to a given standard. This system favours a limited range of rpgs which follow the 3-18 stat range, but I don't see that as a big problem.
The variations of the beasts in this collection is good, everything from crazy undead stuff to intelligent (perhaps even) playable creatures, which is always good. I for one is looking forward to the next instalment in what I hope is a series of beardy beast collections.
Of course there can be some challenges in how to tweak and fit each creature into a given system, that does not conform to the standard this "systemless system" is based on, but testing, good intentions and time should be enough.
