The Daedric Princes in The Elder Scrolls series really feel like the Titans of Greek mythology. They are more forces of nature and and not really concerned gods. A few would count as really evil, depraved gods that don't like their own followers, though.
The quests they put you on in the game are generally really nasty. They get in your head and try to get you to kill your companions. They try and force you to sacrifice good priests, especially Boethia, the cannibal. I really like how they are implemented in Skyrim, and they should provide a great base for DMs to model evil gods and priests on.
As I've said before, DMs who need inspiration owe it to themselves to play Skyrim, especially the side quests (the main quest with the dragons is not even the best questline in the game, IMO).
