You know, I may be an old roleplaying fogey these days, but I would love to see the old "All The World's Monsters" see the light of day again.
Monster books these days are too po-faced, trying to be zoological textbooks. With ATWM, anything went - you had straight po-faced scientific writeups of giant beasties, and then wild and whacko monsters from just about any source of inspiration - comic books, B-movies, fairy tales, science-fiction, whatever. It fed the imagination and had something for everyone (I still love the "Coachman of Death", if only for the Sleepy Hollow atmosphere).
Three books. Everyone contributes something, everyone gets credited. Favourite monsters all over the place. Would be way cool.
Now where did I put those writeups for Replicants, Aliens, Daleks, Tusken Raiders and Jawas...? Reckon I can change them names if I have too...
