Reading Lob's and Pichard's comic book adaptation of Homer's Odyssey from the pages of Heavy Metal has got me thinking what a great setting science fantasy Greek myth might be. Not recasting the myths into a science fiction context or something like that, but bringing a little Jack Kirby twist to the proceedings. Maybe a fantasy world that's post-apocalyptic, but where the apocalypse was the Titanomachy.
The heroes (the PCs) would be hapless Bronze Age Achaeans who are playthings for high tech cultures (aliens or extradimensional beings) who are there gods. Guys that look sort of like this:

Beings descended (or created) by extradimensional monsters like this:

In addition to Ulysses above, the Orphans of Chaos series (where universe creating Saturn is a rebel against his hyperdimensional species that stands outside of time--and wants to destroy it) by John C. Wright would be a could inspiration. Any of Jack Kirby's mythology related works are also essential, particularly The Eternals.
