The wait between Grand Theft Auto V and GTA 6 has stretched over 13 years—an eternity in gaming. While many have pointed to the success of GTA Online and multiple re‑releases as the reason, a former Rockstar developer offers a different, more technical explanation: Rockstar may have rebuilt its core technology from scratch.
A Complete Engine Overhaul
In an interview with Kiwi Talkz, former Rockstar audio designer Rob Carr—who worked on L.A. Noire, Red Dead Redemption, GTA V, and Red Dead Redemption 2—shared his speculation on the extended development cycle.
“I know nothing about it, other than the fact that they probably will have – given the time frame of how long it’s taken them to get to this stage – they’ve probably rebuilt the entirety of the Rage Engine,” Carr said. “That’s the only thing I can say with real, genuine confidence.”
He added that he would be “amazed” if they haven’t, because “the architecture of technology has advanced significantly since GTA 5.”
The RAGE (Rockstar Advanced Game Engine) has powered every Rockstar title since Table Tennis in 2006. While it has been continuously upgraded—most notably for Red Dead Redemption 2—a full rebuild would represent a massive undertaking, requiring years of foundational work before any game content could be created.
Why This Matters
A ground‑up engine rebuild would explain several things:
- The extraordinary visual leap seen in GTA VI trailers, where even small details like towel fibers and phone reflections show generational improvement over RDR2.
- The rumored $2–3 billion budget, as rebuilding a proprietary engine while simultaneously developing a game is enormously expensive.
- The multiple delays, as unforeseen technical challenges with a new engine would ripple through every aspect of production.
It would also align with Rockstar’s history. The jump from GTA IV to GTA V saw significant engine enhancements, but that gap was only five years. A full rebuild would naturally take longer.

The Final Stretch
Whether or not the engine was rebuilt, the finish line is finally in sight. Take‑Two CEO Strauss Zelnick has repeatedly reaffirmed the November 19, 2026 release date and confirmed that marketing will begin this summer—an unusual public commitment that signals genuine confidence.
For fans who have waited over a decade, understanding the scale of the technical achievement behind GTA VI may help the remaining months feel a little shorter. If Carr is right, Rockstar hasn’t just been making a game—they’ve been reinventing the tools to make it.
