It appears Zynga believes it owns the exclusive right to any game ending in the term: “Ville”
According to Gameranx.com, Zygna filed a federal law suit last Friday against Kobojo the maker of the game, PyramidVille.
Zynga says in their complaint:
“Facebook users are likely to believe, erroneously, that PYRAMIDVILLE is a member of Zynga’s ‘VILLE Family of Games,”
In a statement Zynga said:
“Zynga’s “Ville” family includes many well-known games, including FarmVille, CityVille and CastleVille, and the “Ville” suffix is strongly associated by gamers with Zynga.
“Given Kojobo’s refusal to change their game name, legal action was necessary to defend our famous marks and prevent player confusion.”
