It is not an overgeneralization. It is likely true, and I often say in the office that the advent of the surge popularity of the video game, texting and other smart phone activities is leading to the downfall of the social fabric of America. Overdramatization, perhaps. But, consider that many of my patients can't look up from the DS, a parent was snacking on popcorn while on the phone and parents discipline their children by taking away the very thing that has caused them to have disciplinary products.
I don't have children, so it probably isn't fair to say this, but I don't think I would allow them to play them until a certain age. Same thing with cell phones or at least until they could pay for them. Personally, and I could be wrong, I don't think they make kids safer.
