Also I get the feeling you were going for something akin to a 1 for 1 between the 6 ship systems and the 6 attributes, would a good simplifier be to treat a ship as a plAyer with each system using said stats? Say for npcs.
So something about current ship combat, I'm assuming a weapons check that's described would be say computer use + proficiency or +/- the crew modifier from the ship, as would the counter roll be navigation + proficiency or +/- the crew modifier from the ship?
