Censorship issues regarding video games tend to be based on concerns that minors will be harmed by exposure to video games with violent speech and images. Many parents and community watchdogs fear that children who frequent the make-believe world of video games will replicate the games’ violence in the real world.
Rating Association, an independent group. The ratings are intended to give consumers information about content and degree of maturity of intended users. However, state and local legislators have seized on these ratings to propose restricting sales of some games to minors.
Nintendo of America's policies of strict video game "censorship" have become one of the infamous tactics of this period. While often overlooked back in the day, the rise of ROMs, especially Japanese ROMs, have exposed many gamers to numerous examples of Nintendo censorship in practice.
References to smoking or sex may have been removed from the Japanese version of a game prior to its release in the United States, while other games with potentially offensive content may simply have not been released at all. Although Nintendo's censorship practices have often been condemned as inconsistent, or at worst hypocritical, they actually stem from a document that outlines the rules in explicit detail.
Examples include the Super Nintendo port of Wolfenstein 3D. In this port, all blood and gore and Nazi symbolism are removed, guard dogs are replaced by mutant rats and Adolf Hitler has been renamed "Staatmeister". As such, this port is considered by many Wolfenstein fans to be the worst version of the game.
Another example is the Super Nintendo port of Mortal Kombat, all blood in this version is replaced by "sweat" and the fatalities became less violent "finishing moves". This heavily damaged the reputation of the Super Nintendo, as well as decreasing its sales incredibly, in contrast to the superior Sega Genesis port.
In the Japanese version of Super Mario Kart, the victory animations of Bowser and Toadstool's animations depict them drinking champagne. Because Nintendo of America's censorship policies didn't allow depictions of drinking in games, these animations were changed in the international versions of the game.
