The sprawling setting of EVE Online is called New Eden, a galaxy with over 5000 known solar systems. This is a vast area for players to pursue their goals, but given how each of those solar systems is clearly mapped out, some of the feeling of being in such a deep setting is lost. There's not enough sense of the unknown. It's possible to be an explorer in the game, but the fact is that truly new places aren't discoverable, just hidden pockets within the known galaxy. That will change in the Apocrypha expansion this March, when a true exploration system based around wormholes is implemented.
