Gran Turismo is a racing simulator developed by Polyphony Digital and designed by Kazunori Yamauchi, released for PlayStation in 1997 as the debut entry in the long-running Gran Turismo series. Following five years of development, it became the best-selling PlayStation game, shipping over 10.85 million copies worldwide as of March 2013. The game offers two distinct modes: Arcade Mode, which lets players freely select from available cars and courses, with victories unlocking additional content; and Gran Turismo Mode, a more structured career experience that requires players to earn tiered driver's licenses before entering sanctioned events, then accumulate credits, trophies, and prize cars through championship racing. The full roster spans 140 cars and 11 tracks, each available in both standard and reversed configurations, providing a substantial variety of competitive circuits across both modes.
