A general name for any sim or virtual world that is believed to encourage negativity, vice or dangerous behavior including the encouragement of addiction and crime. Much controversy can surround this label or accusation for a developer, for example with many fantasy game worlds featuring positive or creative requirements despite being based in a negative or law-breaking scenario. Such examples can be said to even prevent real episodes of crime, despite a few infamous or stand-out cases allegedly being attributed to it. On the other hand, such publicity can boost sales and promote the game world. It is agreed across the board, however, that Bedlam4 type experiences are far too vivid or extreme.
