Yeah, I know it's not a "logo-logo" for mass brand kick-assery, I meant more along the lines of the title screen logoface like you said.
I did a few designs on paper, but the problem I have with Roger Dean style stuff in general is the readability of some of his logos.
You can't do a simple print with that.
(When I think official brand logos though I imagine if it'll work as a faxed letterhead or even a business card. Not that it'd be on any, but it should be readable at that size.)
For in-game menus and stuff I want it to have the color, texture and shape of a Roger Dean title illustration, but I might not even do that for an official logo.
But I think that's a good idea, to start outside of the pixel medium and work backwards. The BIG problem is the title is long as hell and hard to get readable and within a certain space.
Also, the illustration I was shamelessly borrowing from is:
And by "borrow" I mean practically copying. :<
