Almost three-and-a-half years have passed since Pac-Man Championship Edition first hit Xbox Live Arcade. Debuting as part of 2007's Pac-Man World Championship, the reimaging of Namco's classic title, Pac-Man CE was an instant hit. After its initial run, the game was included on a pack-in disc with the Xbox 360 Arcade model as well as later appearing on the Namco Museum: Virtual Arcade compilation disc. Seeing the success of Pac-Man CE, Namco went back to the drawing board with the intention of making Pac-Man CE even better. Thus, Pac-Man Championship Edition DX was born.
