Hows about having a huge hulled ship with a manufacturing module that can make up to medium class ships.could make things easier when u conquer a planet far away from your sphere of influence and then find owt the planet has 1 basic factory on it and several starports and other low tech buildings.100 turns l8r it will be a productive planet unless you can afford to buy all the upgrades.whereas you could move your manufacturing ship to a nearby location and be able to churn out defenders for the planet or even move it into orbit and say halve the production time of all social building work.Of course these would have to be dear to maintain but could add an edge to gameplay.Only an idea.any thoughts please discuss
