According to a new report in the Korea Times, online video game publisher NCsoft has seen its stock price almost halved over the last two months "as investors raised doubt about the prospect of its online games business."

NCsoft's Lineage series has been a huge generator of revenue, earning the company more than 1.5 trillion won since 1997, but the games are losing subscribers and the company is hoping that Tabula Rasa in the U.S. will help lift the company. NCsoft also recently purchased the rights to City of Heroes/Villains from developer Cryptic Studios.

Nevertheless, concern over the company's games business "losing vigor" have led it to invest in non-game Internet services. NCsoft this year has already released a series of social-networking services from Openmaru (an in-house software studio) including MyIDnet, Life Pod, Spring Note and Rolling List. The focus on the social networking services reportedly comes with "strong support" from NCsoft CEO Kim Taek-jin. "The Openmaru studio is the first step to create a more open Internet environment by providing easy-to-use technologies," he said.

For its part, NCsoft insists that its primary focus is still games. "NCsoft's main business has been games, and will be games," PR chief Kim Joo-young, told the Korea Times. "Our sales are 100 percent from game business."
