We've heard a lot about the rapid growth of the game business in North America, but China? According to a new study, online games in China boomed over 60% to hit $1.66 billion (US) last year. Some online game developers there grew by nearly 600% in a year.

What's even more compelling is the business model behind a lot of these games. Rather than charging off the bat, they give away the games for free and sell players items in microtransactions. This is surely the way of the future.
