One aspect of the Kingdom will be that players and GM's alike will have the option to create custom space faring vessels for their campaigns.
Much like character creation ships are created with a series of dice rolls. Depending on the skill of the creator, their knowledge of human and alien technology, and whatever manufacturing capabilities they have they can create anything from a simple fighter to a technologically advanced cruiser of immense size.
Basic stats will be available for each category of starship (example: fighter, freighter, patrol ship, cruiser, etc.) along with details on individual systems and weapons that can be used to personalize the vessels. There will also be a special "innovation" chart that contains special abilities or technologies that some creators can utilize if they get a high enough roll.
GM's will find this system easy and intuitive to use for creating vessels for their players and NPC factions. Utilizing the system there will be thousands of different potential vessels you can create.
