The gaming world was a tad surprised when Batman: Arkham Knight was awarded an “M For Mature” rating by the ESRB earlier this week, but no one has taken up the “Won’t someone think of the children!” mantle just yet. And that’s probably because the way that gamers treat a Mature-rated game is much different from the way moviegoers react to an R-rated film (to say nothing of the dreaded NC-17).

You might even wonder if this has signaled a shift away from the ESRB’s Teen rating (which has always been considered equivalent of the much-more-popular PG-13 for films). Few games carry a Teen rating in 2015 and nearly every critically acclaimed title of the past decade (BioShock, Red Dead Redemption, Fallout 3, Skyrim, Grand Theft Auto V, and many others) has been slapped with a scarlet “M.” Paul Tassi of Forbes believes the “T For Teen” rating is dead and that it’s unlikely anyone will notice or even care:

Unlike the movie industry, however, a game being rated M is not all that big of a deal. Movies will bend over backward to cut themselves down to PG-13 from an R in order to have a chance at dramatically increasing their box office haul, and there’s only one R-rated movie in the top 25 highest grossing films of all time, The Passion of the Christ. There are 16 PG-13 movies, by contrast, including the first four of the top five.

Gaming is a much different story, with rating hardly seeming to matter at all. M-rated games are routinely best-sellers, and comparatively seven out of the top 25 highest selling video games of all time are rated M, all split between Grand Theft Auto and Call of Duty titles, with the non-M games mostly coming from Nintendo ’s E-rated stable. In fact, there isn’t a single T-rated game in the list.
