Lawful Indifferent

I've been wanting to run a pseudo-RIFTS type game) where the players are basically stranded, interdimensional types stuck in a middle world that's being torn apart by some sort of bizarre temporal hiccup that none of them have any idea how to get out from or even fix), but I'm not sure where to go from there. I just have this mental image of cyborgs buddying up with samurai who have a distaste for the tommy-gunning gangster that's schmoozing with the demon-possessed techno-mage, but I don't really know where to go from there.

I do, however, know that it'd be a great setting to play around in and I'd be able to include pretty much anything I could think of, from enormous floating castles to colonies of badger-men to talking trees to shapeshifting doppleganger horrors... but it's hard to get people to really stand behind that sort of deal.

It feels like everybody wants either premade settings where they can act out their fanfictional desires (40k and Greyhawk and stuff), a combat simulator with characters grafted on(4e, 3e, and it's derivitives), or a really hardcore high-concept roleplaying game without goofiness or randomization.

Or they want games they already played in a new package, but that doesn't really count.

I need to get out there and game something already.
