The Virtual Drug

Anyone who has ever tried an online game, especially RPGs knows the feeling:

Are these games "virtual drugs"?

Possible.. And like real drugs, World of Warcraft can also lead to broken families: http://us.i1.yimg.com/videogames.yahoo.com/feature/wedding-woes-the-dark-side-of-warcraft/1186366
