Ummm
What about phone addiction? I have saved a few lives in my time when I stop people before they got hit by a car because they literally were stuck staring at their phone with no regards to their surroundings.
People are WAY more addicting to their phones than games, I see ALL ages staring at their phone in a crowded venue or on a street for almost 10 minutes a clip.
Go do some people watching next time you are out and tell me how many people were not glued to their phone. (Could just be a NE USA thing I supposed as well.)
TL;DR
Phones are much more of a problem than video games if we want to use China's logic.
