The China’s game market reached 203.6 billion RMB (about $30.9 billion) in 2017, increasing by 23 percent compared to the previous year and leading the world in total game revenue, according to a report on China’s games industry.

More than half of game sales last year, 116.1 billion RMB, were mobile games, said the report co-released by a national games committee and data companies. The contributions of PC and web games to the total revenue dropped significantly to 31.9 and 7.6 percent, respectively, mainly because gamers are shifting to mobile devices.

The mobile game market maintained high growth in 2017, boasting an increase of over 30 billion RMB, up 41.7 percent compared with 2016. What’s more, overseas sales of online games developed in China reached 54.1 billion RMB or almost $8.3 billion in a single year, 118 times greater than the $70 million in 2008.

Most insiders believe that it’s amazing to score such a boom within a decade. Other cultural products like well-made domestic films have never grown that fast overseas.

Online games have been the main force of China’s cultural industry and are leading the trend of going out, said Lv Benfu, Director of Research Centre for Cyber Economics and Knowledge Management at University of Chinese Academy of Sciences.

The online game sensation boosted the game industry. A total of 185 gaming companies went public as of the end of 2017, quoting the report. Now, a number of companies are preparing for IPO launches and the sound environment and fast-growing market will drive more companies to enter into the capital market.

The gaming industry remains an emerging industry on an upward trend. However, the fast development of China’s online game industry has some parents concerned about child video game addiction and early exposure to violence and eroticism.

Parents may not worry about their children if the games provide fun as well education. With more cultural elements and knowledge added, young players can learn something when advancing to the next level, said Hong Kong film director Stanley Tong, adding that game developers need to think about their social responsibilities while developing games.
