Gaming does have positive attributes, providing a chance to socialise with friends and create virtual playdates as we look to keep in touch with those who are important to us. For single-child households this is particularly helpful as they get the chance to mix with people of their own age.  Rewards in the brain are released which provide feelings of happiness. These can come from winning a game, completing a level, getting the desired item from a loot box or winning virtual currency.  But the player can then quite easily get addicted to playing as the brain craves that feeling more and more.
