WHile it's pretty obvious there have been breakups due to too much gaming, it could be anything, video games just happen to be the thing here, besides this is a report from the Daily Mail, therefor making it total bullshit. The Mail, The Sun and The Star are not reputable newspapers, remember the Daily Mail is the same news paper that made up the GT Rothberg story, they are nothing more than Fox News in Britain, leave htem alone unless you're ridiculing them.
Also that list is just...odd. Relation ship splits over Mario Kart? Assassins Creed? Fucking Angry Birds?
