I think a nice addition to the game would be a mission board, as well as a log to accompany it.
The mission board could be:
-pre-determined needs for a Obonto,
-a package delivery mission,
-a personnel transport mechanic
-ETC.
These could pay varying amounts, being a nice way to make some consistent money. i'm imagining a bounty board sort of setup, but whatever fits into the game engine best is best.
Perhaps the board would have its own guild that you could join, with higher paying but more dangerous missions:
-armed escort
-derelict ship transport
-clearing out a pirate meeting spot
-ETC.
