You never read any Raymond E. Feist books?I know all of those settings except for Riftwar, and I'll have to go with Stormlight. Although if we're talking Sandersson I believe Scadriel in the Wax&Wayne era would be even more fun. I really enjoy magic and revolvers…
I'll pick the "something else" option, the fantastic Babylon Five universe. We don't have enough future/space-faring games, and this setting is so incredibly rich, I'm amazed someone hasn't done it already. This is something I'd through money at just to reward the attempt!!! (assuming it wasn't done by some laughable company/persons, ie, Electronic Arts, Lucas, etc).
I haven't read any Ursula K. LeGuin stuff but I have seen a few shows she wrote. Can any settings be made from her work?

The last game made in his setting was called Betrayal at Krondor in 1993.
