Obviously, here at WoW Insider, we're fans of the game, and it's hard to blame an inanimate object like a computer for serious problems in someone's life -- while World of Warcraft is one of the easiest ways an addictive personality can manifest itself, millions of people around the world are able to play it and maintain healthy lives and relationships.
Still, if you're playing World of Warcraft (or doing anything else) so much that it's affecting your health or social life, it's time to stop and/or get help from an organization like this. We won't blame the game for causing someone to pass out (common sense says that doing anything for 15 hours straight isn't good for you) or do poorly in school, but if either of those things are happening to you, in Sweden or anywhere else, because you're playing the game, then cut it out.
