A common assumption today is that the majority of people who either buy or play computer games and video games are children or young teenagers. In fact, well over sixty percent of all those who do play or buy such video games are over the age of eighteen. It is largely the older brothers and sisters, or even parents of the children who are the majority of gamers. When you look at the type and range of video games and computer games on the market, there is a large variety, some of which are suitable for children and families, but many of which are not, and in the case of video games which do feature more mature or adult content, this is clearly displayed on the cover label. Shops and retailers have a duty to ensure that games labeled for those only over the age of sixteen or eighteen are not sold to underage children, with proofs of age required in the case of any uncertainty. In reality, this actually happens quite rarely - even more rare than those retailers who check the ages of people buying videos and movies that have similar age restrictions or advice labels on them.
