It seems that some poor sap in the US has become so addicted to Lineage II, that he's played it for close to 11 hours a day since it launched. As a result, he's found himself with difficulty in dressing himself, bathing himself and even communicating with family and friends. What's someone like this to do? Sue NCsoft, of course, for making the game "too addictive".

It'll be fun to see just how quickly this case is thrown out of court. It's not like NCsoft emits drug vapor from your speakers while you play... and it's not like any other MMO is any different. Don't blame the drug, blame the fact that you succumbed to it.
