To some extent I think this mentality will carry on for more generations. When I was in College most of my peers stated they simply didn't have the time to play games anymore. Other friends of mine became much more social and drank all the time and had other things they did.
I, however, didn't play games when I had the time. I made the time to play them. Some people looked at me as if I was destined to fail out of College, but in truth I just managed my time. I did my class work, I played games, then whatever time was left was spent hanging with friends or doing something else. No one stopped going to see movies, but I only went when I had the spare time.
So most people will look at video games as being something sacrificed in adult hood, when you just don't have the time you did when you were younger, but I don't think that will happen to me (of course, that happens when you're spending your unemployed time researching the ins-and-outs of becoming a game writer). Games are here to stay.
It's most troublesome with my family, though. Particularly my father. He tries to draw comparisons between my playing video games and people watching sports, as I've never truly enjoyed viewing them on TV. I try and explain that I'm not watching a video game being played, I'm doing the playing. I'd rather go out and play football then watch other people do it. The only sport I can get into is Hockey, and even then to a very limited extent through the television. It's just easier to enjoy in person.
The holidays are always tough, though. I tend to write out a list of games I'd like and where their black friday sales are going to be for my mom, and he looks at it with shame. As if I'm too old to be making lists. However, no one in my family would ever know what to get me otherwise. I mean, what else would I get for Christmas? I have enough clothes and everything I could use that isn't film or game related I already own (a laptop, Photoshop and a Wacom tablet).
Of course, this is also just part of the difference of being a media junkie versus, well, anyone else. I'll learn how to change my oil out of necessity (assuming it saves money in the end), but I'd rather pay a kid to mow my lawn than do it myself. But film, music and games? I'll analyze and dissect it because that's what I do. That's my fascination. Entertainment is a special brand of art that not everyone gets, and it fascinates me.
But I guarantee you when I'm fifty, whether I'm writing about video games as a profession or not, people will still say the same thing. "You STILL play video games?".
