A video game can change the brain, may improve empathy in middle schoolers. A fantastical scenario involving a space-exploring robot crashing on a distant planet is the premise of a video game developed for middle schoolers by researchers to study whether video games can boost kids' empathy, and to understand how learning such skills can change neural connections in the brain.

With the advent of global obesity in first world countries and considering that the video game industry makes more money than the movie industry, we can deduce that in the future more and more video games will be designed to produce positive health benefits. Perhaps it will be mandatory that all games are similar to the machine in the movie Ready Player One where in order to play the game you need to be on this treadmill like machine.
I will offer the arguement that video games can offer better mental health benefit, over that of psychically health. Whether it be because of how many games can not only be educational, but challenge you mentally. Even with something as simple as puzzle solving, reasoning, strategy, and even learning social skills.
I think the healthiest games are those that challenge critical thinking. Puzzle games are very good for younger teens for brain development.
That being said you should limit the amount of time spent on games. They will become accustom to playing and they will desire more and more.
Games like Minecraft are among the best for kids, believe it or not. It inspires creativity in the mind and requires strategy in order to survive and thrive.
