Grand Theft Auto 3 did not begin as an inevitable blockbuster. Before Liberty City became one of gaming's most influential virtual places, its creators had to convince colleagues that a dense, free-roaming 3D city was even possible. That early argument was eventually answered with a humble Dreamcast demonstration: cars on streets, pedestrians moving through an urban environment, and the basic ability to take a vehicle and drive wherever the player wanted.
Aaron Garbut, Rockstar North co-studio head and art director, has reflected on that pivotal period and the pressure surrounding the release of GTA 3. His memories paint a picture of a young, ambitious development group at DMA Design, newly relocated from Dundee to Edinburgh, working at the exact moment games were rapidly moving from 2D spaces into three dimensions.
For Garbut, launching GTA 3 was a release of years of accumulated tension. The team was relatively inexperienced, he said, and had carried the anxiety that naturally comes with attempting something without a clear contemporary blueprint. But the game's eventual success did more than validate a bold technical gamble. It created many of the production habits, design priorities, and open-world principles that continue to define Rockstar North's work.
A Dreamcast Proof of Concept for a 3D City
DMA Design had already explored three-dimensional development through projects including Body Harvest, and the people behind that work felt ready to bring the original Grand Theft Auto formula into a new perspective. Not everyone at the studio was convinced. The earlier GTA games had experimented with a slightly tilted viewpoint in GTA 2, but a fully simulated city created in 3D brought a far more intimidating set of technical demands.

The question was not simply whether the team could render buildings. It was whether players could hurtle around a city at high speed, turn in any direction, leave vehicles, interact with pedestrians, undertake missions, attract police attention, and still believe that the place around them was alive.
To make the case, the developers assembled their Dreamcast demo over a matter of weeks. It presented the essentials of an urban sandbox: traffic, people walking the streets, and cars that could be stolen and driven. Once it was shown to Sam Houser, then executive producer at Take-Two's young Rockstar Games label, the project received a major boost.
Garbut describes Houser as a figure who has consistently urged the team to push further, take creative risks, and resist settling for a merely adequate result. That backing mattered at a time when GTA's jump to 3D was still a proposition rather than a proven success.
The prototype became a focal point for the team's aspirations. Garbut recalled the confidence of developers who understood 3D technology well enough to see the potential, yet were also young and naïve enough to view the enormous undertaking as exciting rather than paralyzing. Their priority was not initially a checklist of missions or a sequel built rigidly around past conventions. It was the city itself: the "playset" and the "toys" that could make a functioning urban world feel alive.
Leaving Arcade Logic Behind
GTA 3 inherited several foundational concepts from its predecessors. Players were still cast as criminals working for more dangerous criminals. The series already had multiple mission contacts, Wanted levels, and the Pay 'n' Spray mechanic that offered a way to escape police attention.
Yet the developers did not approach GTA 3 as a conventional sequel. Instead of faithfully carrying over every element of the 2D games, they discarded systems that felt too abstract for a close-up 3D world. One notable casualty was the destruction score, which Garbut characterized as a kind of pinball-style scoring system. In an immersive city, constantly tallying points for mayhem no longer fit the desired tone.
That decision reveals one of GTA 3's most important shifts. The move into 3D made space for a stronger sense of cinematic framing, atmosphere, and emotional connection. The player was not looking down at a tiny criminal icon navigating a map; they were physically present in traffic, narrow streets, industrial spaces, and rain-swept neighborhoods.
The team also lacked a direct model for what it was trying to build. There were urban driving games that supported fast movement, and there were denser games that separated intricate areas with less demanding spaces or distinct zones. GTA 3 attempted to combine those strengths. Liberty City was not meant to be broken into neat loading chunks, filled with broad empty terrain, or designed only for driving at speed. It had to support vehicles, exploration on foot, missions, dense streets, and unpredictable interactions in one continuous-feeling experience.
The Streaming Challenge Behind Liberty City
Much of GTA 3's impact came from the feeling that Liberty City extended beyond the player's immediate view. The world streamed in around the player, allowing the game to show distant skylines, waterways, traffic-filled streets, and changing districts without regularly stopping the action for lengthy loads.
That illusion demanded painstaking work. Garbut explained that the art team manually divided the city into pieces in ways that would make the most efficient use of limited memory while ensuring data could be read quickly enough from the disc. The programming team, meanwhile, built the streaming technology needed to manage the world as players moved through it.
The optimization reportedly went as far as arranging files on the DVD in particular orders so related pieces of the world could be accessed together more efficiently. It was an unusually granular solution, but it helped GTA 3 reach an ambitious goal: a city with scale and visible detail that could be explored without the sort of disruptive transitions that would undermine the fantasy.
Of course, the system could occasionally reveal itself in memorable fashion. Players may remember the rare moment when geometry seemed to appear a little too late, sometimes just in time to damage a speeding car. But Garbut remains proud of what the team accomplished. Once the streaming approach was working, it removed many restrictions on scale and detail. The main limitations became what could fit around the player in memory and what could be pulled from the DVD drive quickly enough.
Open-world development is not only about displaying scenery. Garbut emphasized the challenge of managing competing systems and chaos. A mission might need to run cleanly while, just around the corner, traffic creates a pileup, several vehicles explode, and police activity escalates. The game has to keep functioning even when players produce situations no designer explicitly staged.
Cars Turned a City Into a Playground
Rockstar North's development process, as Garbut describes it, begins with the location. Once the place feels convincing enough to inhabit, the team adds the toys that let players engage with it. For GTA 3, those toys were overwhelmingly the cars.
Vehicles were the feature that made Liberty City suddenly feel complete. Garbut remembers the excitement of seeing cars physically behave in the world: skidding, bouncing over kerbs, and displaying different handling characteristics depending on whether the player was driving a truck, a sports car, or another vehicle type.
That may sound ordinary now, but in the early 2000s it was a transformative sight. Vehicle physics gave the player something compelling to do even outside of missions. Cruising, crashing, escaping the police, experimenting with handling, or simply watching traffic behave all contributed to the game's appeal.
Garbut also points to the collaborative momentum this creates in game development. A breakthrough from one discipline inspires another team to respond, improve, and build further. GTA 3 could generate those moments repeatedly, turning a rough prototype feature into something that changed how the entire world felt.
Building New York From a Distance
Liberty City was a fictionalized vision of New York, but its creators did not have the vast online reference libraries available to modern teams. Garbut had only visited New York a couple of times at that point. The studio initially had no internet connection, no Google Maps, and only a small collection of 35mm photographs taken during a trip.
Instead, much of the team's understanding of the city came from film and television. That distance helped define Liberty City's identity. Rather than aiming for glamorous realism, GTA 3 leaned into wet streets, grey concrete, litter, dark water, rain, and the gloomy routine of city life. The dynamic weather system and changing time of day strengthened that mood, while the PlayStation 2's technical limits encouraged the team to prioritize atmosphere over fine visual detail.
The same approach contributed to the series' satirical voice. The aim was to capture an exaggerated impression of America rather than reproduce a literal version of it. Garbut believes that working from television, movies, and a more limited personal connection to the United States gave the team greater control over that impression.
A Rough Foundation That Still Matters
GTA 3's story of Claude and Catalina is comparatively simple by current Rockstar standards, and Garbut readily acknowledges that parts of the game now appear rough or lacking refinement. The silent protagonist was one creative choice the series moved away from quickly. But the game taught the team what worked, what needed improvement, and where the next project could evolve the formula.
Vice City, released only a year later to major acclaim, demonstrated how quickly that foundation could be expanded. Its '80s-inspired setting, costumes, and lighting proved that the same underlying structure could support a radically different atmosphere. Garbut sees the studio's later work, including the ideas visible in GTA Online, as part of a continuous path that began with GTA 3.
His art-school training offers a fitting way to understand that legacy. Garbut learned the value of "roughing in" a work first: establishing its underlying structure before refinement. GTA 3 was as finished as the team could make it at the time, he says, but viewed today it is plainly simpler than the games that followed.
Even so, if players "squint a bit," the foundation is still visible. The living city, the vehicle-driven freedom, the dense systemic chaos, the fictionalized American place, and the willingness to take major risks all remain central to Grand Theft Auto. GTA 3 was not the final form of that vision. It was the bold, imperfect breakthrough that made the rest possible.
