Here's an idea : a module that you can buy for the huge ships that let them have a starship on board that let you build tiny fighters and keep a phew inside the ship. Something like that anyway... Think about it, a tiny ship with one pilot in his tiny cockpit and a huge ship with a huge crew, kitchens, beds, bathroom, medics... huge ships should have this advantage in the game too, like a starship, hangar & repair station module.. and the ability to go anywhere on the map.
edit : nm this topic, I see there's already one made called "SHIP CARRIERS"
