Regulation body China Audio-Video and Digital Publishing Association introduced a new age-based rating system for games in the country this week.
Under these new standards, games will be divided into three age categories, each represented by a colour: 8+ (green), 12+ (blue), and 16+ (yellow). Games must display these labels on their website and "other relevant materials," the South China Morning Post reported.
The new guidelines were announced at the Chinese Games Industry Annual Conference, held in Guangzhou, on Wednesday. The new system has been crafted by giants Tencent and NetEase, as well as 52 other organisations, and is called the 'Online Game Age-Appropriateness Warning'.
The new guidelines are currently in a pilot phase, said first deputy chairman of CADPA Zhang Yijun, adding that the aim is to provide "positive guidance for underage consumers."
