They may, for example, contain classifiable elements such as language and themes that are mild in impact. The impact of PG (Parental Guidance) classified computer games should be no higher than mild, but they may contain content that children find confusing or upsetting and may require the guidance of parents and guardians.
However, some G-classified computer games may contain content that is not of interest to children. G products may contain classifiable elements such as language and themes that are very mild in impact. The G classification is suitable for everyone.
