The exceptionally long development timeline between Grand Theft Auto V and Grand Theft Auto VI stems from a combination of massive technological leaps, hyper-detailed open-world design requirements, and Rockstar Games' meticulous development philosophy. Building a hyper-realistic virtual ecosystem with unprecedented graphical fidelity, complex artificial intelligence, fully simulated physics, and expansive narrative depth demands millions of hours of meticulous coding, motion capture, and iterative polishing across multiple console generations.
