Speaking to Edge, Bethesda has explained what it calls a "misconception" regarding the classification of Fallout 3 in the Australian region. Edge has also learned that due to concerns and issues raised in the process of international classification, Fallout 3 will not contain real world drug references in any territory.
Fallout 3 was originally refused classification by the Australian Office of Film and Literature Classification, citing among other reason the in-game use of "Morphine" in order to ignore limb pain. According to the Office's guidelines, "material promoting or encouraging proscribed drug use" is refused classification.
In mid-August, the OFLC announced that a revised version of the game had been granted a rating in Australia, thanks to edits that changed the context of the in-game drug use.
