'As addictive as gardening': how dangerous is video gaming?

Snooker player Neil Robertson claims a ruinous addiction has harmed his professional career. It's not alcohol, it's not drugs – it is video games. In a recent interview with Eurosport, the Australian said his compulsive need to play the online fantasy game World of Warcraft interfered with his training and preparation for a tournament in China. "I'm two months sober from playing them," he told the site. "My friend said to me: 'you don't get to choose the crack you are addicted to'. And the multiplayer online ones I can't touch because I just get too hooked on them."
