Running a spy agency in the game EVE Online

"EVE is considered by many to be a 'sandbox' MMO, and in such a place, only the ruthless survive. The list of nasty things you can do is only limited by your creativity and your capacity for cruelty." In a persistent world where all deaths are final, ruining someone's day often becomes necessary on the path to glory.

From sophistication on the economics front to this. It sounds like an intriguing game.
