Something I just found over at Paizo:
The Noble Wild, a new RPG sourcebook for playing sentient animal characters in D&D-ish settings. I don't know if they go as far as "anthro critters" or not, but it looks like a good-sized piece of work. Maybe I'll scoop up a copy after AC to see what it's like.
And if anyone here des have a copy, please let me know what it's like.
