Virtua Fighter is a fighting game created for the Sega Model 1 arcade platform by AM2, a development group within Sega, headed by Yu Suzuki. An early prototype version was location tested in Japan by August 1993, before the complete game was released worldwide in December 1993. It is the first game in the Virtua Fighter series, and the first arcade fighting game to feature fully 3D polygon graphics. The game has been ported to several platforms including the Sega Saturn, Sega 32X, and Microsoft Windows. The game was critically acclaimed and a major hit, becoming one of Sega's best-selling arcade games of all time with more than 40,000 arcade units sold while the Saturn versions sold over 1 million copies. Virtua Fighter was highly regarded for its in-depth 3D fighting engine and real-world fighting techniques, and has been revolutionary and highly influential in the evolution of the genre and video games in general. An update titled Virtua Fighter Remix, developed by AM1, was released for the Saturn in 1995, and ported to the arcade later that same year. The game's remake, Virtua Fighter 10th Anniversary, was released for the PlayStation 2 in 2003 as a stand-alone title in Japan and as a bonus to Virtua Fighter 4: Evolution in North America.
