If you want to force a hardcore addict to stop playing, just trick their brain into thinking taking a break is an optimal power move. In the beta of World of Warcraft, players were penalized with half-experience if they played too long without resting. Players absolutely hated it and threw massive tantrums. So Blizzard simply halved the baseline experience and called the normal rate a 'rested bonus.' Gamers praised the generosity, completely unaware they had just been psychologically played.
