A new piece of research delivered this week by Nielson Games suggests that approximately 17% of those buying the adult-rated title IV were underage.

The game was rated '18' in the UK, meaning that theoretically no one under that age should be able to buy the game in a store. 61% of these youngsters were apparently able to buy the game by themselves, the rest being bought the game by a parent.

The 17% figure is likely to alarm parents groups and sections of the media, while it could fuel critics of the present ratings system. PEGI and the currently compete on the front of game boxes for influence.

We'll bring you more on IV as we get it.
