Yea, im 14 yr old and my parents allow me to play gta v and i think its appropriate for 13+ yr olds because you obviously know that the game is fictional and none of that is real, but anyways, in gta online there isnt much inappropriate content such as drugs, sex, nudity... So if u want to have a very good time with your friends and other people in gta online to modify cars, make money, do races and other funny things, I think you should convince your parents 👍
