So i've been thinking of doing a Sci-fi story or series of stories set in space with interstellar travel and space battles. I'd also like to visit various planets and locations if it is a series.

But I'm unsure what kind of main cast I would like. In other words what kind of crew, what is their job? What are my characters doing or their goal in space?

Bounty Hunters?
Treasure Hunters?
Members of the Military?
Law Enforcers?
Researchers?
Smugglers?
Legitimate Delivery men?
Mercenaries?
Pirates?
A Race through space?
Lost in Space?

What kind of story would you read? what kind of Crew would you follow?
this "story" would be done in either comic or vignette format.
