Ever since two players coordinated amongst themselves to visit the exact same spot on exactly the same planet at exactly the same time (quite the feat given number of planets in the game), there's been talk about whether or not No Man's Sky includes or will include an actual multiplayer component.
While remaining painfully vague on the matter, game creator Sean Murray has hinted that a form of multiplayer is in fact a possibility, even though the players who decided to meet up could not see eachother.
This could obviously mean that Murray is pulling everyone's leg, but it seems more likely that the feature has not been enabled yet. Murray talked of overloaded servers when mentioning the multiplayer debate, and the game's limited edition provides furter proof.
