Ragnarok Online 2 is shutting down in Korea. As reported by MMO Culture, Gravity has announced that the Korean servers will come down on December 23rd, and that services in North America and Europe will not be affected by the change. The shutdown notice points to a lack of players as the reason for the service being sunsetted, although it does include the possibility that the game may be revived in the future.
