In truth, the most multiplayer we'll ever see is blueprints sharing. The game is not designed for the kind of multiplayer required to pull off the lore discussed here, and likely never will be. Think about it, what happens when a player logs off? Do his things stay behind for people to blow up? Or do they disappear, allowing someone to build on top of them? And if they stay, but indestructible, think of the clutter from players that leave and don't come back, or players that leave an asteroid belt worth of debris in orbit...
This RPG in the forums is purely a battle of the brains; 'who can outsmart the other's tactics' being what determines the outcome. A game of chess, where there's no board.
