Galactic Command

GCO is a space and planetary combat MMO that takes place in a large galaxy. The game is developed by 3000AD, a company with over twenty years' experience in developing high end and hard core space/planetary combat games such as the Battle cruiser and Universal Combat series, and most recently the All Aspect Warfare games.

It is however not a traditional MMO. For one thing, though the servers are capable of supporting tens of thousands of players, each game "Universe" only allows up to 256 players; though several Universe servers can be linked to form a seamless (to the clients) mesh.

There is no instancing, sharding or waiting in a game lobby queue to play.
