RIFT. As of today, the game has officially started its full commercial service in Korea under the guidance of NetMarble.
The game is also launching with several of the usual launch events such as promotional giveaways, although they're of limited utility if you don't read or speak Korean. It's an unusual export, but with several Korean games making major promotional pushes in the US (such as Aion and TERA), it might be the time to see if cross-cultural appeal works in the other direction. And if you're familiar with the language and want to see how the game plays when adapted, now's the time.
