A whole gray campaign is welcome once in a while. In my book this is considered a one shot that lasted 2 years. I did play Vampire, Werewolf and Cthuluh and there is enough gray in there to entertain those who like gray. As a player I love gray. Especially in Vampire the Masquerade. But as a DM, I prefer a Heroic style where good and evil are clear and easy to identify. Once in while there might be a villain that tries to pass as a good person but I often leave a few hints that it ain't so.
I think this misses something though.
You can still have good and evil be easily identifiable, without having races be default good or evil.
The guy summoning demons to destroy the city, he's evil. But just because you run into an orc tribe doesn't mean they are about to get to some hard core raiding and pillaging.
Individuals can be evil. Groups, harder to tell.
