Video game censorship are efforts by an authority to limit access, censor content, or regulate video games or specific video games due to the nature of their content. Some countries will do this to protect younger audiences from inappropriate content using rating systems such as the ERSB rating system. Others will do this to censor any negative outlook on a nation's government. Overview Support for video game regulation has at times been linked to moral panic. Even so, governments have enacted, or have tried to enact, legislation that regulates distribution of video games through censorship based on content rating systems or banning. In 2005, David Gauntlett claimed that grant funding, news headlines, and professional prestige more commonly go to authors who, in good faith, promote anti-media beliefs. Tom Grimes, James A. Anderson, and Lori Bergen reiterated these claims in a 2008 book examining sociological effects on the production of media effects research. Voluntary regulation Voluntary rating systems adopted by the video game industry, such as the ESRB rating system in the United States and Canada (established in 1994), and the Pan European Game Information (PEGI) rating system in Europe (established in 2003), are aimed at informing parents about the types of games their children are playing (or are asking to play). Some ratings of controversial games indicate they are not targeted at young children ("Mature" (M) or "Adults Only" (AO) in the US, or 15 or 18 in the UK). The packaging warns such games should not be sold to children. In the US, ESRB ratings are not legally binding, but many retailers take it upon themselves to refuse the sale of these games to minors. In the United Kingdom (UK), the BBFC ratings are legally binding. UK retailers also enforce the PEGI ratings, which are not legally binding. Canada The Ontario Film Review Board and the British Columbia Film Classification Office respectively prohibited the sale of Manhunt and Soldier of Fortune to customers under the age of 18, notwithstanding their ESRB "Mature" ratings, by legally classifying them as films and giving them a "Restricted" rating. Ontario, as well as several other provinces, have since adopted laws that allow the ESRB ratings system to be enforceable by law, primarily by making it unlawful for retailers to sell "Mature" or "Adults Only" rated games to customers who are not appropriately-aged.
