South Australian Premier Mike Rann yesterday said MP John Rau would be the new South Australian Attorney-General after Mr Atkinson stepped down from the position.

In the role, Mr Rau will have input on changes to Australia's classification system — including an R18+ rating for games famously opposed by Mr Atkinson.

Gamers4Croydon party president Chris Prior told news.com.au he had met with Mr Rau and the MP was open to the introduction of an adult rating.

"Just over a week ago, I had the pleasure of meeting him personally when I attended an election forum in his electorate," he said.

"He indicated to me that the lack of an R18+ for games seemed absurd, and that it was really just common sense to introduce it, considering the vast majority of adult content is already available under the MA15+ classification."
