Last week GamePolitics reported on a bizarre incident in which more than a dozen prominent game journalists were sent Animal Crossing: Wild World Nintendo DS cartridges which contained a racial slur.

MTV Multiplayer's Stephen Totilo, who broke the story, reports that he subsequently queried used game seller GameStop and the ESRB as to whether the Animal Crossing incident exposes a flaw in the system whereby embedded user-generated content might exceed the content rating.

Both GameStop and the ESRB view the Animal Crossing episode as an anomaly and deny a larger problem. MTV's Totilo writes:

ESRB spokesperson Eliot Mizrachi, told me... “Just as with online-enabled games that allow features like chat, ESRB ratings cannot anticipate and therefore consider user-generated content in the ratings we assign,” he wrote. “Besides, as you mentioned, saving content to the actual game medium is pretty uncommon in today’s games. Most games are read-only with the saved content being stored on the system and not on the game medium itself.”...

The ESRB may not have much reason to worry that questionable content will make it to consumers because gaming chain GameStop claims to be scrubbing the content from re-sold games. Chris Olivera, spokesman for GameStop, told me in a phone interview that his company has a “proprietary” process that wipes consoles and games clean before they are sold back to consumers...

GP: GameStop and the ESRB make a good case here. It's important to remember that the offending DS cart was not purchased through retail channels, but rather was mailed out by Nintendo's own PR department.
