Eyjolfur “Eyjo” Guðmundsson, an academic, a gaming buff, and an in-house economist for CCP Games, describes his job as being just like “a research scientist for a central bank.” Except his bank and its currency don’t exist in the real world.

Guðmundsson oversees the function of InterStellar Kredit (ISK), the in-game money forEVE Online, a science fiction-themed game world whose average player spends three hours a day online. Approximately 500,000 users worldwide use the platform to constantly plot, scheme, and attack each other in ways that would make the NSA and CIA proud. The game's creators, Iceland-based CCP Games, built an online environment so complicated it requires a real-life security squad and even official, in-game economists--like Guðmundsson. They watch and learn tactics of the biggest rascals so they can take that knowledge into the broader virtual world. While the CIA was worrying about World of Warcraft being used for money laundering, EVE players were busy committing virtual currency fraud to defeat their online rivals.
