Pan European Game Information (PEGI) is a system that was developed to standardize the game ratings in all of Europe (not just European Union, although the majority are EU members), the current members are: all EU members, except Germany and the 10 accession states; Norway; Switzerland. Iceland is expected to join soon, as are the 10 EU accession states. For all PEGI members, they use it as their sole system, with the exception of the UK, where if a game contains certain material, it must be rated by BBFC. The PEGI ratings are legally binding in Vienna and it is a criminal offence to sell a game to someone if it is rated above their age.
BPjM and USK (Germany)
Stricter game rating laws mean that Germany does not operate within the PEGI. Instead, they adopt their own system of certification which is required by law. The Unterhaltungssoftware Selbstkontrolle (USK or Voluntary Certification of Entertainment Software) checks every game before release and assigns an age rating to it - either none (white), 6 years of age (yellow), 12 years of age (green), 16 years of age (blue) or 18 years of age (red). It is forbidden for anyone, retailers, friends or parents alike, to allow a child access to a game for which he or she is underage. If a game is particularly violent, it may be referred to the BPjM (Bundesprüfstelle für jugendgefährdende Medien - Federal Verification Office for Child-Endangering Media) who may opt to place it on the Index upon which the game may not be sold openly or advertised in the open media. Unofficially, the titles are not "banned" - adult gamers are still technically free to obtain the titles by other means, although it is still considered a felony to supply these titles to a child.
