The content of games with a PEGI 3 rating is considered suitable for all age groups. The game should not contain any sounds or pictures that are likely to frighten young children. A very mild form of violence (in a comical context or a childlike setting) is acceptable. No bad language should be heard.
Video games that show violence of a slightly more graphic nature towards fantasy characters or non-realistic violence towards human-like characters would fall in this age category. Sexual innuendo or sexual posturing can be present, while any bad language in this category must be mild. Gambling as it is normally carried out in real life in casinos or gambling halls can also be present (e.g. card games that in real life would be played for money).
Game content with scenes or sounds that can possibly be frightening to younger children should fall in this category. Very mild forms of violence (implied, non-detailed, or non-realistic violence) are acceptable for a game with a PEGI 7 rating.
This rating is applied once the depiction of violence (or sexual activity) reaches a stage that looks the same as would be expected in real life. The use of bad language in games with a PEGI 16 rating can be more extreme, while games of chance, and the use of tobacco, alcohol or illegal drugs can also be present.
The adult classification is applied when the level of violence reaches a stage where it becomes a depiction of gross violence, apparently motiveless killing, or violence towards defenceless characters. The glamorisation of the use of illegal drugs and explicit sexual activity should also fall into this age category.
A U film should be suitable for audiences aged four years and over, although it is impossible to predict what might upset any particular child. U films should be set within a positive framework and should offer reassuring counterbalances to any violence, threat or horror. If a work is particularly suitable for pre-school children, this will be indicated in the BBFCinsight.
General viewing, but some scenes may be unsuitable for young children. A PG film should not unsettle a child aged around eight or older. Unaccompanied children of any age may watch, but parents are advised to consider whether the content may upset younger, or more sensitive, children.
Films classified 12A and video works classified 12 contain material that is not generally suitable for children aged under 12. No one younger than 12 may see a 12A film in a cinema unless accompanied by an adult. Adults planning to take a child under 12 to view a 12A film should consider whether the film is suitable for that child. To help them decide, we recommend that they check the BBFCinsight for that film in advance. No one younger than 12 may rent or buy a 12 rated video work.
No one younger than 15 may rent or buy a 15 rated video work.
No one younger than 18 may rent or buy an 18 rated video work. Adults should be free to choose their own entertainment.

It took longer than it really should have but by 2050, humanity has finally colonized Mars. The leader of the effort is an entrepreneur named Jeff Murray. Rather than living on the surface of Mars, People have made their homes underground. The city and all its supporting facilities are buried deep down, safe from the inhospitable climate of the surface. 

Dr. West migrated to Mars recently at the personal invitation of Jeff Murray. Dr. West has been working on important research which he had hoped would lead to a cure for the Alzheimer's disease which has afflicted his wife.
