In today's Internet age, online games can be a change from the pressure of school and work. However, they can also cause problems and unhealthy addictions. This is most clearly seen in the example of South Korea. This country has the world's highest percentage of high-speed Internet services. It has also a high number of game players who are addicted to online games.

In 2004, a young man died after playing online games almost nonstop for 86 hours. A 12-year-old boy stole $16,000 from his father to continue online games which he could not get away from. Such problems are spreading to other parts of Asia as well. In 2005, it was reported that about 80 percent of China's 13.8 million online game players were under 25.

And many of these were said to be addicted. Such numbers point toward a growing problem among Chinese youth.

Dr. Sue-Huei Chen, a psychologist (心理学家), discovered some signs of at-risk people. Such people often go online to escape from their problems. And they usually have no friendship or good social skills. They feel the need to spend more and more time online, so they may be absent from school or family. And they become upset if anyone tries to limit their online game playing.
