The essential public structure to travel the galaxy, Starports allow players to be transported from one planet to another. Transport ships travel in specific Routes, thus you cannot buy a ticket from one starport to just any other starport in the galaxy.
You can buy a ticket to any shuttleport on the current planet. Shuttles can transport you to any shuttleport or starport on the planet.
Starports are also where pilots land their ships, and thus where they go to launch back into space. Travelling by private ship is easier and faster than through transports, and has no cost associated with using the starport. Wait times between transports (starports and shuttleports) is five minutes.
Because so many use starports, especially in big cities such as Coronet, Theed, and the Dantooine Mining Outpost, many players go inside or around in search of other players, to advertise, to sell buffs and other wares, to fight, and other activities. This can make them crowded and noisy, and may lead to lag for anyone with a low specced computer.
