One of the ideas of this project is seeing what literary settings other folks might use for a Star Frontiers campaign.  I think the Honor Harrington books have a great SF feel to them (though lacking much in equal aliens).  The Dune series, the Lensman books, the Flinx/Humanx Commonwealth books by Alan Dean Foster, even the Star Wars, Star Trek, Babylon 5, Farscape, Firefly and Stargate franchises could adapt into fun games using the SF rules.  Anyone done anything with any of these settings?  Used parts of them?  What else out ther that I haven't mentioned?
