Sorry, I shouldn't be trying to dictate your vision of what the game should be about. All I'm asking for is Flash Gordon-style rocketships!
I've read a fair bit of Edgar Rice Burroughs, Michael Moorcock, Lin Carter, etc; you might be interested in this upcoming comic:

But, returning to the rocketships bit, what I'd like is a bit Leigh Brackett; action takes place on weird planets, swords more usual than guns, but there are spaceports, perhaps one per world, some adventurers get to rove about the solar system...
