Zynga has been accused several times of copying game concepts of popular games by competing developers.[204][205] The launch of Mafia Wars sparked a lawsuit from the makers of Mob Wars.[206] An attorney for Psycho Monkey, the creators of Mob Wars, said that in making Mafia Wars, Zynga "copied virtually every important aspect of the game."[207] The suit was settled out of court for $7–9 million.[208] An Ars Technica column said that Zynga's Café World and Playfish's Restaurant City were "nearly identical"; Café World was released six months after Restaurant City.
