Australians woke up to the news that The Walking Dead, the video games adaption of the show based on the comic, was not made available in Australia or New Zealand. Many assumed it may be something to do with classification, and that assumption seems to be correct.
After being asked why the game wasn't available on Telltale's official forum, a member of staff responded with the following...
Sorry, but due to the OFLC ratings laws in Australia and New Zealand, and the fact that this is a mature game, we do not currently have plans to release the game there on consoles.
The Walking Dead has not been refused classification in Australia, in fact it hasn't even been submitted for classification as far as we know. Therefore we can only assume that Telltale didn't think it was worth the cost (and risk) of attempting to classify the game in this country.
EDIT: Many have rightly pointed out that The Walking Dead can be bought in Steam, but the fact remains the game has not been classified, and therefore technically shouldn't be available for purchase in this country. It does, however, remain a bit of a gray area.
It's a shame, because I would probably expect the game to pass through classification at MA15+ under the current guidelines.
