PlayStation game production was designed to be streamlined and inclusive, enticing the support of many third-party developers. An emphasis on 3D polygon graphics was placed at the forefront of the console's design. The console was primarily designed by Ken Kutaragi and Sony Computer Entertainment in Japan, while additional development was outsourced in the United Kingdom. Sony began developing the PlayStation after a failed venture with Nintendo to create a CD-ROM peripheral for the Super Nintendo Entertainment System in the early 1990s. As a fifth-generation console, the PlayStation primarily competed with the Nintendo 64 and the Sega Saturn. It was released in Japan on 3 December 1994, in North America on 9 September 1995, in Europe on 29 September 1995, and in Australia on 15 November 1995. The PlayStation (abbreviated as PS, commonly known as the PS1/PS one or its codename PSX) is a home video game console developed and marketed by Sony Computer Entertainment.
