Some video game genres are founded by archetypal games of which all subsequent similar games are considered derivatives; notably, early first-person shooters were often called ""Doom" clones", while the success of the open-world formula in "Grand Theft Auto" led to the genre of GTA clones. The genre of endless runners is based on the success and simplicity of the game "Canabalt".
