Zynga launches new social games, but still tied to Facebook

Social gaming company Zynga – famous for games like "Words With Friends" and "Farmville" – is rolling out some new games for its legions of users.

Among them: "The Ville" and "Chefville," and a new service called "Zynga with Friends" which will let track frinds scores. The company's second annual "Unleashed" event is a big deal for investors who want to know if Zynga has a plan to make itself less reliant on Facebook, the platform for most of its games.

Erin had the chance to speak with Zynga CEO Mark Pincus and asked him if he's worried that Facebook might not be everything its cracked up to be.
