While the economy is still on shaky ground, the folks at Nexon America are apparently raking in the money from their many free-to-play online games. Last month the company announced that revenues from their games had increased 35 percent compared to the same time period a year ago. Now Gamasutra reports that Nexon America has told them their August revenue numbers were up 32 percent compared to the same time period a year ago.

Unfortunately, Nexon America has chosen not to give specific numbers for those revenue increases nor give out any profit numbers, although Gamasutra notes that Nexon's US sales were recorded as $30 million back in 2007. Nexon America supports a number of Asian-based online games such as MapleStory, Combat Arms, and Mabinogi in the US.

The fantasy MMO MapleStory has 6 million registered users in the US and in July Nexon said they had 70,000 concurrent users play the game at one time. The online FPS Combat Arms has 3 million registered US users and Nexon said they have seen "double digit growth" for the game over the past several months. They have also seen revenues go up for their other fantasy MMO Mabinogi. They are close to officially launching their next game in the US, the online fighting title Dungeon Fighter Online.
