The Mainichi Daily News is running a three part series on online game addiction.
Most of it seems like scare mongering — students who start playing Maple Story and suddenly became poor students. There's even worse with one mother saying this about her game addicted child, "Sometimes, he'll throw the remote control at the TV, overturn the dining table, bite my hand, or try to strangle me. It's enough to get me wondering if he'll kill me."
Sounds like there are deeper issues here than online gaming...
