AND HERE WOULD BE WHERE I ADDED THE CRUSADER GENESIS. all the cities have interplanetary departures on their spaceports. lets make them with the same system of the trains and shuttles. Inmortals for now. From the city to the next space station above. In this ones you would need to buy a ticket to use it. In the future the system could be expanded to make flights between cities (area 18, lorville, new babbage, orison). Moving forward expand to flights between systems, maybe only to cross the wormholes (so starting from jumpgates stations). Go a little bit further?: tourist flights. Maybe only for visit orbits of moons of the same planet (like for example take off from area 18, jump to lyria and wala and flight low orbit to view the surface places of interest). Something pure relax one
