Not all games have ratings; some independent developers produce games without official ratings. But most major game publishers employ rating systems such as the Entertainment Software Rating Board (ESRB) in North America or PEGI in Europe. Games rated by these organizations usually display a logo with an appropriate age range on their packaging or website page.
Despite their importance, however, there is no universal game rating system. Each country has its own system based on local attitudes to gaming content, so it's important to research the local rating before buying a game for younger players. Moreover, it's important to remember that while a game may be rated suitable for young children, it may still contain mature themes that could disturb them emotionally or psychologically if they don't understand them properly.
Ultimately, Game Ratings are just one tool parents can use when deciding which video games their children should play—or not play. It's still up to parents and guardians to make sure that any video game they allow their child to access is appropriate both in terms of content and skill level needed to play it successfully. After all, no rating system is perfect or infallible!
