Paizo has just released Bestiary 4 and I have to ask the question, do we really need another monster book? Between Bestiaries 1-3, Tome of Horrors Complete and ToH4 I am not sure I feel like plopping down another $40 for more of the same. I am sure some will say, sure the more the merrier, but I feel about the same way I did about Monster Manuals 4 and 5 which I did not get. Seems to me Paizo with this and Mythic are more and more playing to nitch marketing rather than to the core.
