Free-to-play online publisher Nexon America (Maplestory, Dungeon Fighter Online) revealed that its revenues grew 26 percent for the second quarter of 2010 ending last June.

While Nexon America, which is the Stateside arm of South Korean developer and publisher Nexon Corp., hasn't yet provided exact revenue and profit numbers for Q2 2010, it noted that in June alone, its revenues were 36 percent higher compared to the same period last year.

This announcement continues a trend of increasing revenues for the North American division -- last May, the firm enjoyed an increase in revenues to $45.5 million for 2009, a 31 percent growth over the $34.3 million it cashed the previous year

Nexon America's free-to-play titles include MapleStory, which claims more than seven million registered users in the region; Combat Arms, which has over four milion registered users; and Mabinogi with one million users. It also recently launched Dungeon Fighter Online here, and will begin a closed beta for Vindictus next month.

"Our player base and revenues continue to expand, which tells us that gamers find that our free-to-play business model fits their play needs," said Nexon America's CEO Daniel Kim, according to a report from Games Beat.
