The South Korean Ministry of Culture, Sports and Tourism has decided that gaming addiction has gotten to epic levels, so they will be enforcing a ban on online gamers, especially MMOs. Underage gamers will find their Internet connections disabled for six hours every night.
It goes beyond just a simple connection ban. If you play for more than six hours at a time, your connection will be throttled. This ban applies to 19 specific games, including MapleStory and Mabinogi.
