"Pac-Man World" began as a prototype platform game for the PlayStation, titled "Pac-Man Ghost Zone", which was only shown at the Electronic Entertainment Expo in 1997 and intended for released in the fall of that same year. Headed by Namco Hometek director Bill Anderson, the game followed a teenager being sucked into a "Pac-Man" arcade cabinet by the ghosts and their leader the Ghostlord, and transforming into Pac-Man. The game was made to break the mold of previous "Pac-Man" games, such as having a grittier look. Namco's Japanese division put pressure on the project with strict guidelines — Anderson recalls being unable to use a 3D render of the character as a reference, requiring the team to make it themselves. Development was assisted by designer Scott Rogers, with music composed by Tommy Tallarico. When the prototype was presented to Namco, they became unhappy with it and cancelled it for quality reasons, firing the entire development team aside from Rogers, an artist and a programmer. Namco also pushed the release date back to 1998 to allow the game to be reworked. The team decided to revamp the project with a new gameplay engine.
