With the threads around recently about Archdevils and Demon Lords, it made me wonder whether evil gods were redundant. Archfiends have far more "hands on" adventure potential, since they're not as untouchable as gods, and can lead to entertaining high level romps in the Nine Hells and the Abyss. Likewise, Cthulhu mythos style Great Old Ones (or equivalent, like Tharizdun) taking the place of campaign world evil deities seem to have a lot more adventure potential than evil gods, with cultists and the threat of them being summoned or awakened from slumber in the depths of the ocean...
So I ask you - evil deities, what good are they?
