Eve Online is a video game by CCP Games. It is a player-driven, persistent-world MMORPG set in a science fiction space setting. Characters pilot customizable ships through a galaxy of over 7,500 star systems. Most star systems are connected to one or more other star systems by means of stargates. The star systems can contain moons, planets, stations, wormholes, asteroid belts and complexes.
Players of Eve Online can participate in a number of in-game professions and activities, including mining, piracy, manufacturing, trading, exploration, and combat (both player versus environment and player versus player). The character advancement system is based upon training skills in real time, even while not logged into the game.
Set more than 21,000 years in the future, the background story of Eve Online explains that humanity, having used up most of Earth’s resources through centuries of explosive population growth, began colonizing the rest of the Milky Way. In turn, this expansion also led to competition and fighting over available resources as it did on Earth, but everything changed with the discovery of a natural wormhole leading to an unexplored galaxy named “New Eden”. Dozens of colonies were founded, and a structure was built to stabilize the wormhole that bridged the intergalactic colonies with the rest of human civilization, a giant gateway bearing the name “EVE”. However, when the natural wormhole unexpectedly collapsed, it destroyed the gate. Cut off from the rest of humanity and supplies from Earth, the colonies of New Eden were left starved and disconnected from one another; some died out entirely. Over the millenia the descendants of the colonists managed to survive and rebuild their own societies, but the memories and knowledge of humanity’s origins as well as their own from Earth and the Milky Way became lost. Five major distinct societies rose to prominence from the colonies, each growing into interstellar spaceflight-capable civilizations. The states based around these colonies make up the five major factions in Eve Online: the Amarr Empire, the Caldari State, the Gallente Federation, the Minmatar Republic and the Jove Directorate
