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.
A VPN is going to add so much lag that the vast majority of online games would be rendered unplayable anyways. You could play turn based games, MMOs, and maybe some old school rts games, but that's about it.
So this ban isn't trivial to get around.
I used to play LoL with a free VPN, my ping went from about 20 to 40-50, so not too bad
