Keep in mind that this change only goes for Zynga's presence on Facebook. Other social platforms have not yet required Zynga to change its primary payment methods to their native payment methods.

Facebook has also signed similar five-year deals with social game developers Crowdstar and Playdom in an effort to make its digital dollars the primary virtual currency on the platform. With its Facebook Credits even in Target stores everywhere, it may truly be only a matter of time before total Facebook domination (well, in the social world at least).
