What's behind China's new online gaming restrictions for kids?

Hong Kong — China's crackdown on online video gaming was in effect Thursday. Everyone in the country under the age of 18 — more than 268 million people, according to Chinese census data — is now restricted to just three hours of play per week. 

Children can game only on Fridays, Saturdays, Sundays and national holidays — and only between 8 p.m. and 9 p.m. on those days. Access to online games now requires real-name verification and log-in systems, and gaming companies can only allow youth players their three hours of service within those small time windows.  Reaction to the new rules has been mixed. Some Beijing parents told CBS News they agreed that their children's time was better spent exercising or studying, while others criticized the move as government overreach into family life.
