My little brother wants to download this game, So he asked me to do it for him. He is under the age of 16. Is this restriction overly protective and its fine to play, or should I tell him that he is too young?

My wifi was terrible, like always, so while my friends were playing I decided to draw Sova in the woods after a good run in the morning, shirtless because of personal reasons. ​ https://preview.redd.it/kdw6tourikm81.png?width=3000...
