And what would that purpose be? besides 'so cool' worldship.
Issues/possible uses of worldships
Economically... this is a big issue
They are constructed planets... they don't even have to move.
If you reach your maximum population on all your worlds, build Worldships to increase you productivity without getting any more territory or any more tech. If that's all they are then it is rather pointless to even give them engines, call them artificial worlds and just fill them in your most defended system (100 'worldships' at the capital)
They'd have to be limited in some way
(perhaps they can't mine... unless they are using asteroids that aren't being used otherwise, and they need maintenance)
To construct a worldship, you use a world... basically you don't 'build' a worldship, you convert a planet into a Worldship.
So that the Use of a world ship centers around a mobile
economy as opposed to just more
uses for a Mobile economy...
Resupplying/reinforcing a fleet by getting closer to the frontlines (indicating an important part of a worldship may be a shipyard.)
Moving threatened assets away from an enemy attack
That's all I can think of... both of those fit with the 'mobile planet' idea (indeed they fit even better, since that allows you to take assets you have and Make them mobile).... so instead of 'building a worldship' from scratch instead "Convert" a planet into a worldship. (or maybe convert a moon into a worldship... that might be a lower tech version)
there are also story purposes (some species could Start with a Worldship as their HW.. but that alo works.)
