Interesting, it's because it offended morality and decency. Also telling is that they didn't include it in the media release. The legal reasoning sounds similar to the Obscenity Laws that exist in Australia. It must havea been pretty bad or they are really frigidly dense"In the Board?s opinion, Saints Row IV, includes interactive, visual depictions of implied sexual violence which are not justified by context. In addition, the game includes elements of illicit or proscribed drug use related to incentives or rewards. Such depictions are prohibited by the computer games guidelines." ) [media release]
The computer game is classified RC in accordance with the National Classification Code, Computer Games Table, 1. (a) as computer games that "depict, express or otherwise deal with matters of sex, drug misuse or addiction, crime, cruelty, violence or revolting or abhorrent phenomena in such a way that they offend against the standards of morality, decency and propriety generally accepted by reasonable adults to the extent that they should not be classified."(Australian classification board 2013) [website]
hmmm reminds me of fallout 3 being banned until the drug names in game was changed but it seems this is more severe. Hmmm guess i might have to import a UK or USA version depending on how things pan out.
