Back 10-15 years ago, there was a dance craze thing that was supposed to get America moving and solve obesity. I forget the name, but the one where foot pads light up and you step on them. (ETA: Dance Dance Revolution)
A few years after that, Wii was supposed to get America moving and solve obesity.
Now, Pokemon Go is supposed to get America moving and solve obesity.
Yeah, right.
Personally, I don't see any problem with playing Pokemon Go. I haven't bothered playing it myself. I don't even have a smart phone; just a dumb one. I'm 60 years old and not into pursuing cutting edge tech. But I was driving by the local park this evening after picking up some Chinese take-out for a late dinner, and I wondered why people were standing around in the park in small groups in the dark, staring at their phones. Then I remembered about Pokemon Go and I was kind of tickled to see it going on right there in front of me.
But still, it's just one more overhyped fad. The Pokemon Go fad will eventually pass, and something even newer and better will come along in another year or two, and it too will supposedly get America moving and solve obesity. Because that's how we solve obesity in America--with games and toys. And meantime Americans keep getting fatter and fatter.
Seriously: If people want to get physically fit, then they should put down the phone and the toys and get a gym membership. And then visit the gym and work up a good sweat a couple times a week for the rest of their life. That's how it's done in real life. No games, no strolling around the city staring at your phone. Just good, honest sweat on a regular basis. Video games are good for downtime; I still play World of Warcraft on a daily basis for fun at dinnertime. But don't confuse computer or video games with a real workout. It's just doesn't work that way.
I'm not trying to be cynical or mean here. I'm just saying: Be realistic in your expectations of the game. The Pokemon Go fad will pass in a matter of a few weeks or months at most, and people will still be fat. If people really want to get in shape, they need a gym membership, not another video game.
