A video game content rating system is a system used for the classification of video games into suitability-related groups. Most of these systems are associated with and/or sponsored by a government, and are sometimes part of the local motion picture rating system. The utility of such ratings has been called into question by studies that publish findings such as 90% of teenagers claim that their parents "never" check the ratings before allowing them to rent or buy video games, and as such calls have been made to "fix" the existing rating systems. Video game content rating systems can be used as the basis for laws that cover the sales of video games to minors, such as in Australia. Rating checking and approval is part of the game localization when they are being prepared for their distribution in other countries or locales. These rating systems have also been used to voluntarily restrict sales of certain video games by stores, such as the German retailer Galeria Kaufhof's removal of all video games rated 18+ by the USK following the Winnenden school shooting.

Similar to other forms of media, video games have been the subject of argument between leading professionals and restriction and prohibition. Often these bouts of criticism come from use of debated topics such as video game graphic violence, virtual sex, violent and gory scenes, partial or full nudity, drug use, portrayal of criminal behavior or other provocative and objectionable material.

Video games have also been studied for links to addiction and aggression. There have been a multitude of studies concretely linking violent video game play with increased aggression. A meta analysis of studies from both eastern and western countries yielded evidence that "...strongly suggests that exposure to violent video games is a causal risk factor for increased aggressive behavior, aggressive cognition, and aggressive affect and for decreased empathy and prosocial behavior."
