I am getting into the rules for creating and playing a starship as a PC.
This involves considering what a starship can do (about) the circumstances that are occurring inside of it. Without the ability to manipulate objects a player of a starship is limited to turning system on/off, opening/closing door and airlocks (!) and just plain talking.
A couple of Edges that come to mind that would add flavor and interest to playing a starship include:
Internal Manipulators: Whether they are mechadendrites, cyber-limbs, or invisible effect-fields, these allow fine manipulation of internal objects, and are a basic melee weapon.
Internal Weapons: These are wall and ceiling mounted shooters, for intraship defence.
Remote: A wireless controlled robotic body with very basic characteristics.
NB: In recent playtests I also created a starship character with the old 'Remote', and then also let them buy Synthetic (or the remote looked and behaved like a Human). This was interesting for the player, as they were allowed to roam around. I made a rule that a Positronic Core had to be unique, and that the personality within it was either stored in the starship, or downloaded to the Remote, but not both at once (or it led to schizophrenia!)
Then again, maybe I am doing this all wrong, and the fun in playing a starship is that it is a starship, and different to anything else?
