NBA 2K3 presents a simulation‑focused style of basketball built around realistic pacing, player behavior, and situational control. The game introduces new mechanics intended to expand on-court options. Players can dive to save balls headed out of bounds by pressing the jump button in specific situations. A double‑crossover mechanic lets ball handlers chain moves to bypass secondary defenders when driving the lane. Post play includes the ability to fight for position by pushing the analog stick up or down, allowing offensive and defensive players to maneuver for better placement before receiving or contesting passes. Passing now includes chest‑high and bounce‑pass variations, activated by pressing the pass button with different levels of pressure.
The game received "favorable" reviews on all platforms according to video game review aggregatorMetacritic. It was nominated for GameSpot's annual "Best Traditional Sports Game on GameCube" award, but lost to NFL 2K3.
