	The RMT or secondary market for in-game MMOG assets has been controversial for a number of years, with many games such as Eve Online and World of Warcraft forbidding trading that violates their End User License Agreements (EULA). Other publishers such as Sony Online Entertainment previously forbid the sale of virtual goods until 2005 when it opened a new service called Station Exchange allowing the sale of virtual goods. In 2010, the Supreme Court of South Korea ruled that virtual currency is the equivalent of real money and legalized real money trading. In 2011, Blizzard Entertainment changed their decision to outlaw the sale of virtual goods and implemented real money trading (RMT) to their game Diablo 3 allowing users to sell items at an official auction house in exchange for real money.
