Warner Bros. is appealing a ban on one of the most anticipated game releases of the year, Mortal Kombat, as the federal government's censors defend their decision to ban Mortal Kombat while allowing a sexy spanking game to be classified PG.

Earlier this week it was revealed that the Classification Board had given Mortal Kombat a "refused classification" rating due to its violent gameplay, effectively banning it from sale in this country unless the publisher, Warner Bros., submits a more toned-down version.

Spanking fun ... a grab from the trailer promoting the We Dare game

At the same time, a new risqué title for the Wii, We Dare, is due for release tomorrow and has been given a PG rating despite the game promoting spanking, stripping and sexual partner swapping .

The Australian Christian Lobby said the We Dare decision showed the classification system was "broken". Even the game's publisher, Ubisoft, says the game is intended for an "adult" audience.
