CCP is trying something ambitious -- but that doesn't seem to be making quite the waves it ought to. It is linking its successful MMO, EVE Online, directly and fundamentally into its next game, Dust 514, a console shooter.
Players in EVE and Dust will interact directly. If you play the sci-fi shooter, which will launch on the PlayStation Network as a downloadable game, you will be able to accept mercenary jobs from EVE players, or even join EVE's player-driven corporations. The economies of the games are unified, and the battles fought in Dust will have consequences for the players of EVE who run the corporations that sponsor them.
