i think kids my age should be aloud to play xbox games over 12

I want to play xbox games over 12.I think it's unfair for people my age,who want to play xbox games over 12,but can't.they should be allowed to because when Im bored I can play one.But I can't because they're rated 12 and over.The only ones I can play are the dumb games so plaese make all games pg.
