I would go further. Two ratings: Nothing, and AO. AO is strictly regulated and sold only to 18+ with ID. If parents are "worried" about content they can research the game themselves - the game rating organisations are too strict (SSBM for Teen?) and not in touch with the public. Watching trailers should give a fair idea of the content for the whole game.
The government shouldn't be giving advice on purchases nor determining what is appropriate for children except on the 18+ border.
