Chinese online games are practically unknown compared to top titles such as World of Warcraft (developed by a US company) and Final Fantasy XIV: A Realm Reborn (Japanese). But China's game companies are striving for a bigger slice of the global video game market, currently worth $64 billion, according to DFC Intelligence research firm.

China is already a key player in the video game market, with 490 million users and earnings of $13.7 billion last year, figures released in the 2013 China Games Annual Conference show. Domestically developed games grew by 29.5 percent to $7.9 billion between 2012 and 2013.

On his big translation projects, which involve hundreds of thousands of Chinese characters divided among several translators, Dyer says the work is "intense". While chasing tight deadlines, he usually spends six days a week pounding the computer keyboard for up to 12 hours a day. This goes on for two to three weeks at a time.

Fluency in Chinese alone isn't enough to get the job. Clients look for translators who also understand the world of crafting video games.

"In translation, people want to believe in your language skills. But that's just 50 percent," Dyer says while sipping a cup of coffee. "They also want to believe in your knowledge of their industry. That's what is going to allow you to really get what they're trying to say, the subtleties of it."

His career took off quickly, he says, because it's rare to find a translator who has also worked at a video game company. Plus, he was trained in computer and information science in college and holds a master's degree in East Asian languages and cultural studies.
