Being a parent can feel, at times, like leading an authoritarian nation of one. You control what your subject can read, who they can speak to and what they can do; you deal with periodic revolts against your rule and occasionally engage in a simulacrum of democratic decision-making while knowing that you control the outcome. But for all that authoritarian leaders like to present themselves as a parental figure for the country at large, it's rare that they actually get involved with the day-to-day work of, well, parenting. Which is why the news that China is taking on the job of limiting gaming time caught the attention of so many parents I know. According to state news outlets, online gaming companies will be required to limit under-18s to just three hours of playtime a week, between the hours of eight and nine in the evening on Friday, Saturday and Sunday.
