Thanks to Reuters for its article discussing video games rated 'T' for teens containing 'explicit' content that's not noted on the game box

for videogames: "Although most of the games' content matched their ratings, [the survey] found that 48 percent of games contained some content that was not noted on the game box."
The piece goes on to note specific examples: "For instance, 12 of the 81 games showed the use of substances such as tobacco and alcohol, while only 1 game had received that type of content descriptor from the ESRB. And while the researchers reported sexual content in 22 games, only 16 had received a sexual content descriptor"
