SAN FRANCISCO -- Video game publisher Electronic Arts Inc sued Zynga Inc on Friday, accusing the social gaming company of copying key elements of EA's "The Sims Social" game for Zynga's own title, "The Ville." EA's lawsuit is the latest in a series of copycat accusations leveled against Zynga, a company that has shrugged off similar litigation in the past as it grew into the dominant publisher of games on Facebook.
