Chinese 'facebook' friends hooked on games

Richard Gao has a problem. He owns 10 vehicles, ranging from a Harley-Davidson to a luxury SUV, and they are constantly in danger of getting parking tickets.

"I have to keep an eye on my cars all the time so no one gives me a ticket," said Gao, a PR professional in Beijing.

Fortunately for Gao, these tickets exist only in the virtual world of an online game called "Parking War." Unfortunately for Gao, so do his cars.
