There's a well-known open secret that every kid in South Korea have perfectly memorized either their mom or dad's citizen ID (the full 13 digits). There's also a statistic that the distribution of age in kid's popular online games is centered around the 40s/50s... you get the idea. Children usually borrow IDs/phones from your parents or other adult acquaintances (whether it be with or without permission.) Though PC-bangs (Internet cafes) are where you can't get away with this restriction - usually they check your IDs and kick all minors out when it becomes 10pm. What really sucks for kids in South Korea is that cram schools (hagwons) also end at 10pm (another national restriction) - which means that after a stressful day in hagwon they have no time to actually play without circumventing the rules...
