3. The Dresden Files, of course
This is actually being worked on. It's supposed to use the Fate system (a la Spirit of the Century).
I don't know that system, but I'm not at all surprised. The novels and setting are practically designed around creating an RPG -- a worldwide organization with designated ass-whoopers (Wardens), and if you want to run a low-power game, there's Paranet! It's like Ars Magica Madern! (Or, like the antitesis of Mage, but that's not coincidence.)
If the system doesn't suck ass, I can harness my natural laziness and quit working up my ORE homebrew.
As for a licensed game that doesn't blow, preach on, preacher! Trouble is, it's more work to make a good product, and then the PR people have to deal with it being panned on message boards by all the mouth-breathing purist fan-boys typing with one hand.
I'd imagine a lot of licenses also "protect the property" by ensuring that the licensee is yoked to the story already told. (Though I remember reading that the license for the first B5 game just required "major" additions and changes to be run by production staff for approval, so maybe not.)
