Weird 2010's gamer nationalism meets china bad.
"Oh no, kids won't be able to use games to escape reality now" — Good, have them play outside or read a book or something.
"Horrible, I couldn't live without games" — Yes, this law is attempting to help people before they become like you.
"New generations won't grow up to be gamers now" — How will society survive!
"It's about controlling freedom of thought" — Ah, yes, this will stop the great dialogue had by fourteen-year-olds in LoL game chats.
Honestly, the move is literally a good thing. Online games are addictive and that addiction hurts the people most vulnerable the hardest. Kids are fucking vulnerable as it is, and online gaming is the easiest addiction for them to fall into. Is 3 hours a week too low? Yeah, for sure. But it seems like a reasonable starting point. Maybe it can be loosened in the future.
