A federal government review of research into the effects of violent video games has been too hasty to dismiss studies showing links to aggression, the Australian Christian Lobby says.

Classification ministers across Australia are considering the need for an R18+ computer games rating.

Fallout 3 was banned from sale in Australia until it was modified to remove objectionable content.

The highest rating for computer games in Australia is MA15+ and many are rejected for sale because their content is deemed too violent, offensive or sexually explicit.

The ministers called for a review of available research into violent video games to help them with their decision.
