What is the PEGI rating?

The PEGI rating, short for Pan European Game Information, is a standardized age classification system used across Europe to help consumers make informed decisions about video game content. It provides age-based guidance to indicate whether a game is suitable for children, teenagers, or adults. The PEGI system comprises five main age ratings: 3, 7, 12, 16, and 18, which reflect the appropriateness of the content, rather than the difficulty level of the game. For example, many complex games for adults, such as realistic car simulators, may still carry a PEGI 3 rating.

Each game also includes content descriptors, small icons that explain why a particular age rating was assigned. Current descriptors include: "Violence", "Drugs", "Sex", "Discrimination", "Gambling", "Fear", "Horror", and "Bad Language." These icons are not exclusive to PEGI 18 titles, but nearly all games in that category have at least one or two of them. For instance, in PEGI 18 titles, the "Drugs" descriptor signals that characters use illegal substances, alcohol, or tobacco; those with the "Sex" icon feature explicit sexual activity or full frontal nudity. The "Violence" descriptor in this category indicates extreme, realistic-looking violence, while "Bad Language" may include strong sexual expletives or blasphemy.

PEGI ratings are legally enforced in some countries, meaning retailers cannot sell higher-rated games to underage customers. However, it's important to note that many indie games, especially those not released on console digital storefronts, may not have a PEGI rating. Games must be manually submitted to the rating board, and certification is not free; developers must pay a fee calculated based on the game's budget and distribution type (physical, digital, or both).

What games get a PEGI 18 rating?

PEGI 18 is the highest age rating in the Pan European Game Information system and is reserved for games that contain explicit content meant strictly for adults. Games with this rating often feature strong violence, including graphic depictions of blood, gore, and death. They may also include explicit sexual content, nudity, or prolonged scenes of drug use. PEGI 18 games can depict criminal behavior in a manner that may be perceived as glamorizing illegal activities.

Some games may receive this rating due to realistic violence against human-like characters, especially if it is sadistic or detailed. Strong language, such as repeated use of extreme profanity, can also contribute to the rating. The best examples of PEGI 18 games include Grand Theft Auto V, Cyberpunk 2077, and The Witcher 3: Wild Hunt. These titles are designed for mature audiences and are not suitable for children or young teens.
