I assume it would be the age they think is appropriate for the game you would want, like when I put my actual age it said I was only allowed to play some of the need for speed games. So when I made my new account i made sure that the age would be over 18.
@terqafc thats a bit weird since i am trying to play a pg game but it doesn't let me, thanks for the tip though i will try it! edit: (just looked through all games and i can only purchase/download G rated games so i can confirm it is an age thing. Is there a way i can change my age not through ea help though?)
You can contact ea to change your age but they will ask for a passport or license but I’m not sure about the license
