It wouldn't be hard to make more than their North American branch does sans Guild Wars 2.
The question that arises is: Could Russia be a more profitable market for NCSoft than North America and Europe? Judging from their earnings reports from 20, it very well may be. It is unlikely releases outside of China will carry over its fatigue system. All three are mentioned to be based on the current Chinese build of the game. The release of Blade & Soul in Japan and Taiwan is no secret, but the Russian release is a bit of fresh news.
The earnings report shows Lineage, Guild Wars 2, and Aion as their top earners the conference call reveals Blade & Soul is heading specifically to Japan, Taiwan, and Russia this year - with no other territories listed. NCSoft recently released their 2013 earnings report, along with their Q4 2013 conference call.
