Jacked in

There are tens of thousands of PC "bangs," or Internet cafes, in South Korea, like this one in Busan, the second-largest city. It's packed with teenage and adult males playing games like Diablo 3 on LAN lines. More than 90 percent of Korean children use the Internet, and 10 percent to 15 percent of those are said to be at risk of becoming addicted to games and other online activities.
