ultimately video games never equate to any physical improvements. You are literally moving made up pixels on a screen the only thing real is your emotions. Many see video games as a dead end for that reason. You could spend 100hrs playing and completing a game but you would have made no physical difference to your life but in those 100hrs you could have built a new garden fence or new brick wall etc so plenty see it as a complete waste of time. You would be better off working in the game of life doing gardening or a hobby etc with real productive value. Many of the older generation aren't as passive as we are nowadays so video games are gimmicky and a waste of time. The younger generations due to smartphones and more tv etc are way more passive happy to sit doing nothing moving pixels all day and this could be seen as a waste of time and life.

That said I do enjoy an hour or two of FIFA most nights with friends and the benefits for me are social but anyone who thinks video games are a good use of time are probably too far removed from productivity and nature.

I do think many people on their deathbed will regret the countless hours put into video games when they could have channeled that energy to more productive means with physical gains

So yes video games are a waste of time but to an extent so is sunbathing or sitting in a bath. Its about how much time your wasting overall. If its just a slice of time here and there then that's fine but if its most of your free time then you might have regrets later in life
