A Nintendo game that was pulled from sale in Europe over child pornography concerns is on sale in Australia with a PG rating.

Dead Or Alive: Dimensions, a Nintendo 3DS game, is the latest edition to the Manga cartoon-style combat series famous for big-breasted female fighters whose outfits leave little to the imagination.

But Dead Or Alive raised eyebrows in Sweden, Norway and Denmark because three of the game's female characters - Ayane, Kokoro and Kasumi - were described as being under 18.

This makes them underage under Swedish law, and allegations were raised that game features, which allow players to look up their skirts and take photos, depicted them in pornographic situations.

"Nintendo has taken the decision not to distribute the Dead Or Alive: Dimensions Nintendo 3DS game in Sweden (at the present time)," a statement from Nintendo Europe said.

"As with all games, Nintendo evaluated a number of different factors and decided on this occasion the market conditions in Sweden are not suited for the game, which is developed by Tecmo Koei and distributed by Nintendo."

But Nintendo public relations manager for Australia and New Zealand, Heather Murphy, says those three characters are listed as N/A (no age) for their age in the Australian version.

"In the Australian version of the game... it doesn't state the ages of all the players and the ones who do have an age in their profile are not under 18," she said.

"They're not listed as underage, they're listed as no age.

"Nintendo didn't rate this game. Tecmo Koei didn't rate the game. The classification branch did.

"They're a government body and look at the content and have given it a PG rating."

Dead Or Alive hit Australian shelves on May 26.

In giving it the PG rating, the Classification Board described the game as depicting "mild violence and sexualised gameplay".

The board has been contacted by ABC News Online but is yet to respond.

Home Affairs Minister Brendan O'Connor has been made aware of the child porn claims and is asking for answers.

"The Minister is concerned about the content reported in the media," a spokesperson told ABC News Online.

"The Minister has been advised the Classification Board has asked for further information from Nintendo about the game.

"The Minister will consider taking further action once that information is provided."

Last week Mr O'Connor's department released draft guidelines on the introduction of an R18+ rating for video games, ahead of a meeting next month to decide whether to push ahead with the new laws.

Games that do not qualify for the current MA15+ rating are not sold in Australia, but the higher classification would drastically loosen restrictions on drug use, nudity and language.

Currently, all states and territories need to agree on the classification for it to go ahead.
