It is rare to find any chief executive officer - let alone one leading a company with 800 employees - finding the time to spend three to four hours a day playing games. But Kevin Chou does.

Chou, CEO of Kabam Inc, a US mobile gaming developer and publisher, describes himself as a very "product-focused" leader and he is now bringing the same level of focus to the China market.

The San Francisco-based Kabam, which earlier this year officially launched its first game, Marvel Contest of Champions in China, is expected to bring another game to the country in Spring 2017.
