Also, I love the idea of massive systems, and removing all current code wrecks, and adding new ones in the far distant systems, that are really powerful.
Those are both spectacularly epic ideas, especially if a LOT of these systems are made, like so many that they would take months for any one person to chart, especially without nav maps.
However, I don't like the idea of current codes being made faction controlled, IMO, they should be left as they are, just simply having the wrecks removed/made not to drop codes, so that there is suddenly a limited number of them, and they become really valuable (plus it gives a certain 'player-run market' feel), which would coincide fantastically with the introduction of new codes in these far far out, vast, unexplored systems.
