Convince my father of Valorant?

So I already have Valorant and have already played it and he just came in yesterday and said that it was like Counter Strike and I should knock it down right away. I don't think he was serious, and I'm almost 15, and Fortnite used to be able to play what I do, too. Very sorry

Show your father that blood effects and corpses can be switched off. These are the only reasons why the game is released from 16 and not from 12. (and of course since it is a first person shooter, which you can't change)
