Japan’s LINE Corp, the parent company behind the popular LINE instant messaging service, has taken off as one of the most popular social networks in Asia over the past few years, largely in part to its fabulous collection of stickers and booming business as a mobile gaming platforming. Home to hundreds of games these days, the company has announced a further $100 million that will be dedicated game development and other investments of that nature. One such investment is a 10 percent stake in Gumi, the developer behind one of Japan’s most popular free-to-play RPGs, Brave Frontier. The studio will now develop exclusively for LINE’s mobile service.
