Eve

EVE Online is a massive multiplayer online game that offers limitless potential to discover, explore and conquer an amazing science fiction universe
The world of EVE Online centers on a dense cluster of star systems connected to one another by a vast network of stargates.

These gates allow for near instantaneous travel between linked star systems, of which there are over 5,000 in the network. The core of this cluster, called New Eden by its inhabitants, is controlled by four major empires that constantly vie with one another.
