Researchers from the UK, Germany and Portugal have developed a game that helps children identify and thwart bullying in schools by using role playing. The game, "FearNot!" is being tested by 1,000 children all over Europe.

From the article:
Bullying is an often underestimated problem in the everyday life of school children. Studies show that this behaviour can be found in nearly every school and that the incidence is considered to be quite high. Bullying can take many different forms including name-calling, spreading rumours and lies, as well as threatening, blackmailing and beating up other children
In the specially developed computer game “FearNot!” each child takes the role of an invisible friend of the victimised character, discussing problems and exploring possible solutions and coping strategies. The advice given subsequently influences the actions of the victim.
