Pac-Man wasn't given a voice in the game due to Namco being unable to decide what he should sound like — some suggested that he sound like an adult male and others like a human child. To save money on voice acting and animation, the character was made to be speechless. Tommy Tallarico was hired back to compose the soundtrack. The game was first shown at the 1998 Electronic Entertainment Expo (E3) tradeshow in Atlanta, Georgia, under the working title "Pac-Man 3-D". Rogers recalls it being a popular title, saying that many play testers shared with him their memories with "Pac-Man" series. It was then shown off at E3 1999 under the final title of "Pac-Man World: 20th Anniversary". The game was released in North America on October 15, 1999 to coincide with the original release of "Pac-Man" in the United States. It was later released in Japan on November 2, 1999 and in Europe on February 28, 2000. A Game Boy Advance version was developed by Full Fat and released in 2004. The PlayStation version was digitally re-released on the PlayStation Network in 2013, part of the PSone Classics brand.
