"You are attributing a sense of activism to Valve/EA that frankly, they just don't have or is far too easily overridden by their desire for money."
The latter could unwillingly create the former. If a cost-benefit analysis shows that it just isnt worth modifying and resubmitting a game, publishers simply wont release a game in Australia. Midway's Narc never saw a release in Aus after it was RC. Though the scenario is unlikely for a high profile game, its not out the question. Especially with Digital Distribution.
"Pfft, complaints do nothing. Imagine the unbelieveable explosion of piracy"
From the OFLC 2007-08 annual report
"The Classifcation Board received 169 complaints in relation to the classifcation of computer games.
136 complaints were received in response to reports that the publisher of Grand Theft Auto IV modifed the game for classifcation in Australia in order to gain an MA 15+ classifcation. These complaints also referred to the absence of an R 18+ classifcation for computer games.
Seventeen complaints were received about the RC classifcation of Soldier of Fortune and seven complaints were received about the RC classifcation of Dark Sector. These complaints also referred to the absence of an R 18+ classifcation for computer games.
Single complaints were received about other titles. These include that Alone in the Dark (M) was classifed too low, that Postal 2:Share the Pain was classifed RC, that the computer game Bully: Scholarship Edition (M) received a classifcation due to the themes in the game and that the content of Bioshock (MA 15+) was too violent.
The Classifcation Board also received 553 complaints that were specifcally in regard to an R 18+ classifcation for computer games. 550 complaints were concerned about the absence of an R 18+ classifcation for computer games in Australia and called for its introduction. Three complaints did not support the introduction of this classifcation category for computer games."
http://oflc.gov.au/www/cob/classification.nsf/Page/InformationCentre_AnnualReports_AnnualReports Though the OFLC itself doesnt have the power to introduce an R18+, they are closely linked to the Attorney-Generals Dept. who legislate the ratings system.
edit: the 07-08 report is a fascinating read for anyone interested in the subject. It's unfortunate that the OFLC has to bear the brunt of the complaints, despite not actually being opposed to an R18+.
