A concerned video game retail clerk set out on a mission to inform parents about the graphic content in M-rated games like Grand Theft Auto.

In a letter the employee wrote on Kotaku's website , he candidly states, "I sold too many copies of GTA V to parents who didn't give a damn." 

The letter begins with how much the employee loves his job especially when he sells kid-friendly games like Mario, LittleBigPlanet and Pokémon to children who have been saving up for months.

Then, he transitions to the downsides of his occupation.

The author explains that while M-rated games like Halo, Skyrim and Fable are less of a threat, others like Duke Nukem, Saints Row and Grand Theft Auto may not be suitable for children.

The clerk laments that his store sold over a thousand copies of GTA V, "at least a hundred of which were sold to parents for children who could barely even see over my counter."

As required of a video game store employee, the clerk explains that he reads the warnings from the ESRB ratings box to customers but also includes more specific aspects such as the game has a first-person view of half-naked strippers and a mission that forces you to torture another human being.

Responses like, "It's for my older son" or "All his friends already have it," are common according to the author who wonders how often the youngest child watches the "older son" playing or if "all his friends" were to jump off a cliff.

The concerned employee finishes his letter by referring readers to Penny Arcade where they can learn more about game ratings and whether certain games are good or bad for kids.

Before signing off as "Your Average Video Game Retail Veteran," the author's final request is that "you look at the box, ask an associate for guidance, or just be more involved."
