I mean a fighter build out the highest tier minerals, bsp. avorion xanion etc.
With that you need the minerals to repoduce the fighter.
The idear to have diffrent hulls like, small fighter, normal fighter and heavy fighter, with diffrent atribute bonus and malus would be a idear to.
SMall fighter 100 hp space 3,bonus 15% faster movment and bonus to maneuvering.
Normal fighter 150 hp space 6 no bonus
heavy fighter 200hp, space 8 -15 % movent and maneuver malus...
With the hull the size of the used docking space goes up and how many you can storage, same think with engines.
THe fighters should be bigger than a little drone.
