the trend now is that most young people are holed up in their rooms because of videogames as it's much easier to socialize with people on the comfort of their couch.
With that being said, this topic hits home hard for me. My younger brother (who just turned 18) has always been social recluse because of video games and my parents just allowed it just so he didn't do the same dumb shit I did growing up (underage drinking, partying, etc). The consequence now is that he's completely awkward with everyone except for people online that he's never met in person. My mom is now afraid to send him off to the real world because she doesn't think he can take care of himself because he doesn't know how to do the most basic things such as cooking, paying bills and being responsible. He talks about going into the "real world" and owning a house and my dad says he doesn't know how to swing a hammer, work a saw, and anything that has to do with being a homeowner.
With that being said, it doesn;t make my brother any less masculine than the next person, but being holed up playing video games all day has stunted his personality and social skills so much that we believe that he's going to have the hardest time adjusting to the "real world" and taking care of himself and possibly others.
