Development of the game began with a team of 20 people. However, as the game was getting closer to its release date, the development team gradually increased to between 40 and 50 staff members. Unlike "Resident Evil 2", which features two discs with two different protagonists, "Resident Evil 3" is a single-CD game that centers mainly on Jill Valentine. Capcom chose Jill as the protagonist of the game because she was "the only suitable character remaining", noting that "Resident Evil" protagonists Claire Redfield and Chris Redfield were previously chosen for "Code: Veronica". "Resident Evil 3" was featured at the Tokyo Game Show in March 1999. A playable version of the game was available at the Electronic Entertainment Expo in 1999. At the time, the dodging feature had not been completed and was absent from the demo. To promote the game, Capcom included a brief demo of "Resident Evil 3" in the US shipments of their earlier game "Dino Crisis", which had a successful launch in Japan. Prior to the release of the game, Capcom spent million on advertisement campaigns for "Resident Evil 3" and "Dino Crisis", as well as the Nintendo 64 version of "Resident Evil 2". The marketing campaign included dedicated television advertising, print advertising, and incentives to the consumer. A double soundtrack album for the game, composed by Masami Ueda, Saori Maeda and Shusaku Uchiyama, was released on September 22, 1999. Additionally, a novelization of the game titled "Nemesis" and written by S. D. Perry was published in 2000. "Resident Evil 3" was released for the PlayStation video game console on September 22, 1999 in Japan and November 11, 1999 in North America. The first 500,000 units of the game included additional demo discs of "Dino Crisis". The game was a commercial hit, selling more than 1 million units worldwide by early October. According to NPD, "Resident Evil 3" was the top selling game for the PlayStation in the US during the first two weeks of November 1999. In Europe, the game was released on February 21, 2000 and became a bestseller in the UK, where it received a "Gold" sales award from the Entertainment and Leisure Software Publishers Association, indicating sales of at least 200,000 copies. As of May 2008, a total of 3.5 million copies of the PlayStation version had been sold according to Capcom. Upon its release on the PlayStation console, "Resident Evil 3" received very positive reviews from critics.
