Honestly, this is not an unreasonable take for 1982.
The most recent home console would’ve been the Colecovision and the most popular arcade game would’ve been Donkey Kong.
The NES was still 3 years away and she likely never heard of any of the more narrative PC games of the time like Adventure or Zork.
The only bad part of this take is the insinuation that the only things that last are educational
That was such a weird take from moms of the era. I remember hearing it all the time as a kid, and I thought it was absolutely stupid. Now that I’m all grown up, I still think it’s absolutely stupid.
That was shortly before the 1983 crash goddammit!
Sharon saw the writing on the wall. The game industry flood the market with a lot of crap games and consoles in that time period, leaving to the infamous 1983 video game crash.
