Praelium Suggestions

Unique suggestions (ie. one that you dont either love or hate from another game) for praelium, that need consideration:

Class/Rank - infantry/janitor/thief, komandant/CEO/WarLord
Trade - Regular Imperial transport ships with valuable cargo? (cash to guard/cash to raid)
Atmosphere - Would your engines/thrust work the same on the moon or jupiter?
Time - Ships rust, weapons sieze, planets cross paths and blow up...
Repair Robots - R2D2 was one of these in the Star Wars series (makeshift repairs on the go)
