If it is more serious, it is a crime for online games.
Nowadays, most online games are violent, such as blood, murder, pornography and so on, which will have a great impact on the physical and mental health of minors. Natural selection, survival of the fittest, this is the evolutionary history of mankind. Online games are a test, and passing the test must be the best. But don't forget that "natural selection, survival of the fittest" is the result from a macro perspective, and it took hundreds of thousands of years for human evolution to manifest itself. If online games are left unchecked now, I believe that more than 50% of young people in China will be eliminated, and then most of the outstanding players who pass the test less than 50% will be killed by young people who fail the test in adulthood, or spend a lot of time and energy to solve the resulting social problems. Of course, this phenomenon will not appear. However, it is not the reason of "natural selection, survival of the fittest", but that many people will stand up to resist teenagers playing online games, so whether teenagers will eventually have serious social problems depends on how many people stand up to resist this phenomenon.
In short, online games are still open to minors.
