Gran Turismo is a realistic racing simulation game series created by Kazunori Yamauchi and developed by Polyphony Digital, a studio within Sony Interactive Entertainment. First released in 1997 for the original PlayStation, the series has grown into one of the most respected and long-standing racing franchises in gaming history. Designed to capture the precision of real-world driving, Gran Turismo focuses on authentic car performance, accurate physics, and highly detailed visuals. Instead of just arcade-style speed, it challenges players to understand cornering, braking, and vehicle handling the way real drivers do. Each entry in the series emphasizes careful control, perfect timing, and strategic use of tuning and upgrades.
