What is noteworthy here is that Gravity earned 46 billion won from overseas markets, which accounts for about 80 percent of last year's total sales of 58 billion won. Rather than doing business in the domestic online game market where competition is fierce, Gravity turned its eye to the rest of the world early on so as to actively open up overseas markets. Consequently, the market share of the "Ragnarok Online" game ranks top in the online game area in most Asian countries, including Japan, Taiwan, Indonesia, Thailand, Malaysia and the Philippines. A similar case is that of NCsoft Corporation, Korea's largest game software publisher, which earned about 17 billion won from overseas royalty payments alone in the first half of last year. This figure excluded the earnings of local subsidiaries; if they were included, the amount would likely have been much larger.
