EVE Online's latest Apocrypha expansion has elevated the exploration profession to new heights. The addition of roughly 2500 new and uncharted solar systems, expanding the game's galaxy of New Eden to over 7500 solar systems in total, brings what can honestly be called 'true exploration' to the sci-fi MMO.
Territoriality is a major aspect of EVE and wormholes allow players to emerge in far flung regions of New Eden -- sometimes places they're not supposed to be -- leading to all sorts of unexpected near-death experiences. Players have already reported emerging from wormholes and finding themselves hunted by the local territorial powers (player alliances claiming those regions of the galaxy) or by the NPC authorities, in those cases where players are involved in factional warfare. Some pilots have found themselves deep within enemy faction territory, leading to all kinds of insane chases across the galaxy.
