That's not nearly as bad as Lineage 1: The Blood Pledge. In korea, they have gangs in real life and they actually kill eachother over the game. You can siege castles, and hold them and recieve the taxes that are gained from people buying things in that area. If you attack a powerful pledge's castle, you could very well be visited by some of their "gang" in real life.
It got so bad that a 9 year old committed suicide because he dropped a godly sword (+8 b-katana, if you know about the game). That's definately a game I would NOT get into if I lived in korea =x
