You'll get more health, joy, and life satisfaction out of the capability you develop from an actual skill set than you'll ever get from mashing buttons to make some lights blink.
No, they are precisely limited to what existed in a 1970s arcade. They are no different. The addiction cycle is the same, the pointlessness is the same, the lack of benefit is the same.
What's it like to be dead inside, where every action simply must have a productive outcome? We don't get out of this world alive: have fun while you can, and bring that same joy to others. :P
That's genuinely the quality of argument you want to mount? What, video games have left you unable to make a better account of yourself?
It's funny that you equate learning to do something better than button mashing as somehow being focused on "productivity". The hours you've wasted on blinking lights could have gone to learning a musical instrument or learning woodworking or learning painting, any number of practical skills that have absolutely nothing to do with "productivity" but build you greater capability than pointless, slot machine-like ephemera of no consequence ever will.
Don't try to rationalize the nature of video games as being something more than it is. Recognize it for what it is: a dead-end, go nowhere waste of your time.
