Civilization Online, which has been in "soft" launch open beta for about a year in South Korea, is never going to spread to a worldwide audience. According to Kotaku, the official Civilization Online website has been updated with a notice that all monetary services for the game are now shut down and that game servers will be closing on December 7th.
There is a ray of hope, however, in that the studio may try to relaunch Civilization Online with better game play at some indistinct point in the future.
