Diablo 3 has been facing an uphill battle in South Korea, where the ratings board balked at the auction house feature for its similarities to gambling. The problem has apparently been resolved, as the Korean Game Rating Board now shows the game with an "18-and-up" rating.
The rating (via Kotaku) was granted today. Blizzard had been releasing multiple versions of the game for consideration, and the latest even reportedly removed the auction house feature altogether. The ratings board still felt reluctant, for unspecified reasons. This risked putting a wrench in Blizzard's plans for a worldwide launch.
Whatever the reason, that cautious mood has been taken care of, and the game has been given the green light in the territory. Maybe with that settled, Blizzard will be able to give us a release date.
