Starport: Galactic Empires is a free, space-oriented, massively multiplayer online role-playing game which uses a third-person overhead view similar to that used in Asteroids. The game uses realistic 2-dimensional physics for both space and atmospheric travel, affecting both the movement of ships and player-fired weaponry. Characters can conquer and colonize planets with a variety of different terrains depending on the type of planet. The player can harvest resources, generate money, and produce weapons with their colony. Starport shares many core concepts with Tradewars 2002, notably the commodity trading and planet controlling aspects.
Starport is notable in the MMORPG genre as being one of the earliest adopters of the free to play business model. Instead of charging players a monthly subscription fee, Starport is instead free to play and allows players to purchase extra resources in the game through a feature called "The Admiral's Club."
