I don't care what other people do with their time, but I am SOOOOO glad neither of my kids ever got in to the gaming. They are much more adventurous, preferring basketball and white water sports. It's so much healthier. And besides, I hate watching people sit around idly unless the weather is bad.
I don't really know any grown men (30s - 40s) that do this, but I've heard some wives complain that their spouse is addicted. That wouldn't be something I'd tolerate well. I DO tend to associate video games with college boys and younger kids, and not people who are responsible for themselves.
