ChangYou. The company is a bit less well-known over in the US, but it's still made a name for itself with quirky titles like Zentia and Duke of Mount Deer. It's also apparently making a massive amount of money. According to the company's fourth quarter financial report, ChangYou wound up with a total gross revenue of $435.5 million, with profits surging to $248 million.
CEO Tao Wang says the company can thank a variety of games for its success -- the aforementioned Duke of Mount Deer, an expansion for Tian Long Ba Bu, and the browser-based DDTank. The success of the company in the online market is just part of the ever-expanding Chinese marketplace, which generated over $5 billion dollars last year alone. That's good news for ChangYou and its fans, since the company will enter the next year with plenty of money to generate more games.
