Speaking of fantasy worlds, serious question. Other than books specifically set in FR or other D&D property, how many fantasy novels have anything similar to the number of different races that D&D has?
I mentioned the SpellSinger series from Foster, it was populated with all sorts of anthropomorphic animals. But most fantasy novels I've read? Only a handful. Then again I freely admit my selection is somewhat limited.
Glen Cook's Garrett PI series has lots living in the same city and deals with the issues that feels like it would bring. (I think the first six volumes are spectacular).
