1) Is this normal behavior for the slightly above-average gamer? Unfortunately, it's quite common. People feel that they must be active in these type of events, so much so that they will skip school, stay up extremely late, neglect everyday activities and revision. 2) When does this start to become a problem? When you value a game more than everyday life. 3) What's the worst example of this you yourself have done? I've never been highly addicted to any game, I've played for quite a few hours a day but nothing extreme.
