Currently IMHO bigger ships have all advantages. Harder to kill, more fire power. So I propose a cost for this advantage.
Require all ships to have at least one [ammunition] sign this would cover all weapons on the ship or [weaponset] would also have an ammunition line. Ammunition would have to be preloaded while the ship was not piloted.
Hears is where I am a little torn on this idea. Should the power line be power, ie batteries or should it cost credits. My original idea was power, but power is basically free, so all that would do is add a ship size and maintenance aspect to ships and my goal is to give smaller ships more worth. And I think it is realistic that firing weapons has an economic toll. Something cheap, like 1 credit per laser per shot.
