EVE Online's hands-off economy is trumpeted as a paragon of the Invisible Hand theory. Developer CCP created an incredibly robust backbone for the monetary system, and then stepped back to let players do what they would. Today legions of users continue to buy and sell ISK (the name of EVE Online's currency) for real-world money in countless exchanges online.
But being so laissez faire has its downside. In 2010, a once-respected player completed a complex long con that resulted in his stealing $45,000 worth of ISK from his wards. Last year, one notorious individual led a monumental mass attack designed to devastate the game's economy.
The ploy failed, but the most interesting part was CCP's response upon hearing the plan: "It's going to be f***ing brilliant,"
senior producer Jon Lander told Eurogamer. "Absolutely brilliant."
Only in EVE.
