Videogames are harder to quit than drugs? What has he been smoking?
I lost a lot of seventh and eighth grades to video games, and the final departure from them entailed smashing Starcraft 1 and Brood War CDs in my driveway, in front of my friends, who were telling me "not to waste the CDs." But I needed to do something cathartic, and in my case smashing the discs helped me go cold-turkey. I wrote about it a little bit more here: https://jseliger.wordpress.com/2011/09/04/from-the-depa…
There are also a lot of ways to waste time. Few people seem to make good use of it, so perhaps again it is not really Computer Games that are to blame?
