Gotta admit, I've not yet bothered with the "Races of" series, primarily because I've got my own ideas on handling Dwarves, Gnomes, Humans and the like, and I wasn't really interested in the Goliaths and Illumians. But I am interested in Races of the Wild, if only for the revised version of the Catfolk. And the Raptorans seem interesting.. ...Although I'd seriously re-imagine the race as just bird-people, rather then winged, feathered elf-like folk.
...Kinda makes me wonder if the other Races books might have something worthwhile for me after all...
