Civilization Online is being developed by South Korea-based XL Games, and North American gamers will be disappointed to learn that there are no plans for it coming to the region anytime soon. For now, it's South Korea only.
Accoprding to a statement from 2K Games PR manager Brian Roundy, “Civilization Online is developed by South Korea-based XL Games in partnership with 2K, and will be available first in Korea. No release date has been set. There are no plans for a North American release at this time.”
Of course, Crytek developed Warface for South Korea only, and a Western version was released eventually. XL Games' own Lineage also enjoyed a Western release as well.
