Everyone has hobbies and activities that they like to do. People should not judge what other people like to do in their spare time as long as it isn’t illegal or addictive. Sometimes, people get addictive to playing video games. I would not respect someone who is so judgmental about others so that they have to explain that their hobbies are a waste of time.
The only time when someone should stop or lessen their video game playing time is when they are addicted or they spend too much time playing those games. Then someone needs to intervene. Otherwise, they should be allowed to play those video games. If a video game player stops working their job or communicating with their families, then they may be addicted to playing video games.
