Well, hunting Pokemons can kill people(driving a car while hunting pokemons)

I personally think games who try to fake reality are harmful for a growing brain. All those realistically looking games are not real and fool a growing brain. Parallax, bump maps, ambient occlusion(and almost any technique in those games) are only almost real. I would not let my kid play 3D videogames or VR for more than 1h a day. He has to learn real physics kicking a real ball. Playing with a real Lego is building the neuronal connections of a kid between hands, space and all. While minecraft is building a fake link between 3D space projected into 2D screen surface and a joystick. Two players playing on a video game, are watching for hours the wrong angle of the perspective. The perspective was meant to be seen from the center.

(don't get me wrong, I love 3D games, and I am addicted to them, so I am not playing at all. When I start playing I can play 20h without going to pee. That's why I don't play, because I know myself. I love 3D games, but I would not recommend them to my kids. It is like smoking parents who don't like their children to smoke.)

Still, I am not sure that taxing the game producers is a fair thing to do. Maybe parents have to be penalized somehow.

(Many of logical/puzzle 2D games are actually making the brain think. So they are good for ppl)

I can foresee, people suing the game companies, because they lost their jobs for playing, or because of playing they forgot to take their medicine and almost died.

I wasn't meaning to learn physics for an exam in school. Rather, their bodies to learn how to use physics. Having more realistic for the real world reflexes. An extreme example is to make a real life boxer to fight against a Tekken champion.

VR is ok, after they are at certain age. Still, it produces headaches in adults too. I would prefer kids to manipulate holograms in schools instead of wearing VR helmets. Holograms would be healthier.

That's not "learning physics", it's "exercise". 

You are right! My bad.

The problem of games is that the brain enters in learn mode. For hours and hours the player observes how the hair of Aloy passes through her clothes. Have you never tilted your whole body trying to take a curve in Need For Speed? 
For a movie of bad CGIs, I don't think this is so harmful, because there is no learning for the autonomic nervous system.

When the game is 2D, the player does not lose the notation of reality so much. It is like learning to play the piano. But when the game pretends to fake reality and fails in any technique used, it is then, when in my opinion it could be harmful.

When you observe somebody playing to a 2D game at hard mode, you can see, his fingers working pretty fast. But his torso is reacting little if at all to the game. When you observe how people play CS, you can observe how they are ducking to the side to look behind the corners of the walls. The player ducks behind 3D wall made out of a single polygon, with a triangle rasterized to have straight sides, and in nature, in infinite point perspective, rarely there are any straight lines observed.

For really use body's abilities you have to understand how forces and momentums works.

Not actually. Reflexes and autonomic nervous system are working at their own. Or you are going to tell me that a child that makes its first steps, can explain, inverse kinematics?
