According to Edge Online, the Australian Board of Classification is "under heavy fire from critics" over the MA15+ rating granted to GTA IV expansion The Lost and Damned.
EO describes the situation Down Under:
Critics say that the strong similarities between GTAIV and The Lost and Damned add-on casts light on the disparity at the Australian classification group, a body which had initially refused classification for a number of high profile games such as Silent Hill: Homecoming and Fallout 3.
Yet the Board's handling of the matter may be advocated by the fact that its GTA IV information page clearly shows that the title hasn't ever been refused classification. Rockstar had censored the content before showing it to the classification board, and the game was granted submission on its first attempt.
