BBFC
The BBFC (British Board of Film Classification) is a film and video game classification system used in the United Kingdom. All Grand Theft Auto games have been scrutinized by the BBFC and each one has been given an 18 rating. No Grand Theft Auto games have ever been re-rated or considered for re-rating, unlike in Australia where the OLFC re-rated Grand Theft Auto: San Andreas after the Hot Coffee debacle. The first edition of the game was also re-rated in the USA where the ESRB decided that an AO rating was needed.
