The Blizzard Blog also spoke with the IEAA, the classification board down there for games, and they were told the same thing that Massively was: while the board thought that MMOs did not require a rating, it has since become clear that they do. The difference, says the AG guy, is that the IEAA believed that "games" like WoW were actually services, not games, and thus didn't fall into the classification system.
But now it's clear to everyone that they do, so we'll expect to see the IEAA pass out a rating for World of Warcraft and the other MMOs on sale down there, and then this will all be over. It's interesting to note that ratings may be a very cultural thing -- here in America, ratings are pretty strictly issued by the ESRB, partially because the videogame industry is worried about governement intervention in the system (if the industry can't police themselves, angry parents may ask the government to step in). But in Australia, the government obviously seems largely unconcerned about the ratings. Then again, Aussies aren't completely laid back about everything having to do with MMOs.
