Video games can be totally addictive, are you saying no one wad harmed by Fortnite or World of Warcraft? China is banning video games for kids because it became a national problem. What studies they did to reach that conclusion I don't know but I don't think it was baseless.
Yes, but that's an entirely distinct argument and a different conversation from "violent games are bad because they're violent".
Also note that both Fortnite and World of Warcraft are entirely multiplayer games. The way I see it, their addictive nature comes from the same set of factors that make social media addictive. In terms of addiction, Fortnite and WoW are like Instagram, not like Doom.
After numerous missteps, of which probably the most famous is either the four pests campaign or the birth control ("one child") campaign, I would be very hesitant before assuming any punitive or corrective policy China has any basis in facts or will even have the desired effect.
"According to one study from the American Journal of Psychiatry, between 0.3% and 1.0% of Americans might have an internet gaming disorder."
"Gaming has also been associated with sleep deprivation, insomnia and circadian rhythm disorders, depression, aggression, and anxiety, though more studies are needed to establish the validity and the strength of these connections"
