Amazon is launching a new games service titled Game Connect, not to be confused with its GameCircle service for Kindle Fire. Game Connect has been introduced with the express purpose of helping its users "discover a new category of free-to-play and MMO digital games." Existing Amazon users can link their Game Connect account to unlock rewards, a list of which can be found over here.
The first handful of games included in Amazon's Game Connect service launch are Battlestar Galactica, World of Tanks, Pandora Saga, Stronghold Kingdoms and Super Monday Night Combat. More games will presumably be added as the service grows and develops.
