Does the government have to put a law for the age restriction on videogames?

The videogame industry has evolved over the years, with the first arcade games on the late 1980s, to the VR on our homes. There has been a lot of games, each of them divided on categories. From the games able to play to all the families to the games that are only able for those that reached the adult age. However, this games, that have a lot of adult content are played by teenagers between the 14 years old, and this may influence violent acts on children having by an argument that the game incited them to o that. I would like to know if the government needs to get involved in this situation.
