But it's the long-time video game fans writing this stuff. Even now, "everyone plays video games" is not even close to true. The Entertainment Software Association's own 2009 promotional literature says 68% of US households play video games. That leaves 32% that don't. And that's in the US, still a relatively rich nation where people can "waste" money on game consoles and PCs-for-leisure.
Not so many years ago, it made sense to say "half the people in the world have never placed a phone call". They might have talked on the phone after someone else placed the call in some village out in the sticks. I suspect phones are much more common now, but game consoles and PCs are still expensive luxury devices in much of the world.
So, while we probably can no longer say "half the people in the world have never placed a phone call", I'd guess that far more than half the people in the world rarely, if ever, play video games.
Even in the US, probably a third to a half the population rarely, if ever, play video games. The ESA quotes CBS Evening News as saying "A new study found that more than half of adults play video games, about one-fifth play daily or almost every day.”
Sorry, more than half (in this context) isn't anywhere near "everyone". Some folks need to get out of their insular point of view, get a grip on reality. We can probably say "everyone watches movies now", though there are undoubtedly exceptions. After all, the equipment required is much cheaper, and much less effort is required to participate in the experience. We can't begin to say anything like this about video games.
