Mechanically sound, and clever in many aspects, but I have to say I'm dissapointed in the lore. I'm tired of the old cliche of "Cats view Humans as their worshippers", when both modern behavioral science and any cat lover will tell you this is not true. Cats view their owners as their parents. Giant, non-hostile, super powerful cats who nurture them and take care of them. The relationship between us and our furry friends is much more parent and child.
So to see the tired old "oh, selfish cats, of course they view man as being their servants" just made me sigh. You could easily have kept the arrogancy/heresey of the cats compared to the dogs in Pugmire, by having them view themselves as being Man's chosen inheritors. "Of course we are meant to control the world, we're their choscen descendants! They groomed us as their children!"
But I digress, the rest of the product is solid, and if that part doesn't bother you like it does my cat loving gamer group, it's a great purchase.
