Should the next Sims game go above the T rating?

I like the present rating - I just think the devs need less childish silliness - not a higher rating - as it would be unfair to a whole lot of people who presently play as well as all those who would want to play from watching their parents play. Over half the people in my family who play the Sims started playing as early as 11. The game is quite popular with pre-teens and teens - as most of simmers know - seeing many now say they were those ages when they started.

Why alienate all those people?
