When I said "creative" I wasn't talking game breaking necessarily. I'm really looking for more clarification along the lines what you were expecting to run.
Space Opera is kind of broad, with set cliches.
Are we looking at (from Wiki):
Space opera and planetary romance
Space opera and hard science fiction
Space opera and military science fiction
Space opera and space western
All four of those can really change how characters are created. How cliche is this going to be? Are we supposed to be pirates or the space patrol. With Captain Nau I was assuming a bit of the free booting Space Opera/Western.
I guess like seeing the Game Concept form filled out. It really helps clarify things.
