Black Hawk Mines Reviews regarding China needs online games rating system: Study PowerPoint Presentation: BEIJING: Parents in China are in dire need of a sound age-rating system for online games in order to protect their children, says a new study. China does not have a unified content rating system for the online games industry, which relies on individual games developers to class their own products into suitability-related groups, Xinhua said. According to the report by the government-backed www.youth.cn, only 39 per cent of 423 games were age-rated by the developers. PowerPoint Presentation: Moreover, 51 per cent of those labelled with an age restriction failed to pass a third party evaluation on their ratings, the report said. The report said that 78 per cent of the games should be restricted to adult players above 18, while only two percent were good for children above six. About 80 percent of China's over 560 million internet users are minors, who definitely need more children-friendly or teenager-friendly games, it said. PowerPoint Presentation: The report, however, said the major problems for online games were not violence, pornography or horror elements, and only three percent of the games failed to pass the tests. A majority of the games had "in-game-purchase" traps and many had gambling features. China's online gaming industry earned around 25 billion yuan ($4 billion) in the first half of 2012, the report said.
