You beat me to RuneScape. For the most part RuneScape does it really well.

One of the best written characters in the game is a cave goblin named Zanik, and her group of goblins are largely pacifists. Even some of the “regular” goblins get their characterization explained by the propaganda of Bandos, who is a textbook fascist. I believe the text is called goblin book or something, but even that book tells Bandos followers not to think, and that loyalty should never be questioned.
