The video game industry has witnessed technical innovations that have transformed the way titles are developed and experienced. In this context, Rockstar Games stands out for offering surprisingly detailed and realistic open worlds, thanks to its proprietary graphics engine: the Rockstar Advanced Game Engine, known as RAGE. However, this technology did not appear out of thin air. Its development is a fascinating story of acquisitions, innovation, and an unceasing pursuit of technical excellence.
The Origins: From Renderware to the Need for Change
Before the development of RAGE, the early 3D titles in the Grand Theft Auto (GTA) series were created using an engine called Renderware. This engine, developed in 1993 by Criterion Software, was popular among developers due to its ease of use, cross-platform support, and its ability to create vast worlds with graphics and vehicle physics suitable for its time.
However, the landscape changed dramatically in 2004 when Electronic Arts (EA) acquired Criterion Games, meaning that the rights to Renderware fell into EA's hands. This situation left Rockstar in search of a new graphics engine, just as Renderware began to lag behind the arrival of a new generation of consoles. Files found in GTA IV reveal that, initially, there had been consideration to continue using Renderware for the development of this title.
The Birth of a Legacy: Angel Studios and the AGE Engine
The solution to Rockstar's dilemma was already brewing elsewhere. The story dates back to the 1970s when Diego Angel, a Colombian filmmaker passionate about animation, founded Angel Studios in 1984. This company focused on computer animation and visual effects, even collaborating on film productions such as The Lawnmower Man.
In the mid-90s, Angel Studios made the leap into the video game industry, and by 1996, it began development on its first arcade game: Savage Quest. For this project, they developed their own graphics engine, known as the Angel Studios Engine (AGE), which was refined over time and became the foundation for notable titles such as the Midtown Madness series, distinguished by its semi-open environments and solid vehicle physics.
The success of Angel Studios did not go unnoticed by Take-Two Interactive, leading to a collaboration that resulted in the creation of the Midnight Club franchise, published by Rockstar Games. The relationship between the two companies strengthened, and Sam Houser, co-founder of Rockstar, expressed his admiration for the work of Diego Angel and his team.
The Acquisition and the Evolution to RAGE
In 2002, with the need to replace Renderware, Rockstar Games showed interest in acquiring the AGE engine. Although Diego Angel initially rejected the offer, he eventually accepted a proposal that included the full acquisition of the studio, ensuring its creative freedom. On November 20, 2002, Take-Two Interactive purchased Angel Studios for $41 million, and the studio was renamed Rockstar San Diego.
One of the first projects to adapt the AGE engine was Red Dead Revolver, a western-themed game that had been canceled by Capcom. The team at Rockstar San Diego refined the engine to fit a shooter, improving animations and combat systems. However, the engine still had limitations, such as somewhat rigid animations, which meant that Red Dead Revolver could not open up to a fully free world.
Faced with the crisis regarding Renderware in 2004, Rockstar made the crucial decision to transform the AGE engine into the foundation of its new technology, giving rise to the Rockstar Advanced Game Engine (RAGE), with a team entirely dedicated to its development.
The RAGE Era: From a Ping Pong Table to Immersive Worlds
To formally debut the RAGE engine, Rockstar implemented an unusual strategy: in 2006, it launched Rockstar Games Presents Table Tennis. The choice of a ping pong game allowed the team to focus on optimizing the engine's fundamental capabilities and demonstrate its versatility across different genres, also serving as a technical test for future projects.
The release was a resounding success. The engine surprised everyone with its quality, leading Rockstar to integrate it with the dynamic animation system Euphoria, developed by Natural Motion. This collaboration enhanced the engine's capabilities and improved the gaming experience in subsequent titles.
Significant RAGE releases include:
- GTA IV (2008): Known as "RAGE 2," this version significantly improved graphics and physics, although it had optimization issues not seen in earlier versions. Nonetheless, it was hailed as one of the best engines of its generation.
- L.A. Noire (2011): Although developed by Team Bondi, this game utilized the RAGE engine and showcased the innovative MotionScan technology, which allows for incredibly realistic facial animation capture.
- GTA V (2013): Utilizing what is referred to as "RAGE 7," this title took open-world experiences to a new level of detail and scale.
- Red Dead Redemption 2 (2018): With what is known as "RAGE 8," Rockstar achieved a new milestone in graphical realism, especially concerning lighting and world simulation systems.
The Future is Now: GTA 6 and "RAGE 9"
With the anticipation of Grand Theft Auto 6 in 2025, another significant generational leap in RAGE is expected. Industry sources claim that the game will be based on a new version of the engine, informally dubbed "RAGE 9" by the community, which promises to revolutionize the industry. Although the nomenclature is a fan convention and not official from Rockstar, leaks and the initial trailer already offer a glimpse of its potential:
- Lighting and Volumetric Clouds: An expected improvement based on technologies already seen in Red Dead Redemption 2.
- Ray Tracing and Advanced Reflections: To achieve unprecedented realism in reflections and illuminated surfaces.
- Spectacular Water Physics: A significant enhancement compared to previous titles.
- Individualized Physics: Elements such as hair, necklaces, and bracelets will have their own physical dynamics, adding an impressive level of detail.
- Increased Population Density: The streets of Vice City will come to life like never before.
- Enhanced Visual Effects: From volumetric smoke to more cinematic and realistic explosions.
Moreover, Take-Two has been acquiring patents in recent years that will likely be integrated into GTA 6, further enhancing the engine’s capabilities.
The story of RAGE is a testament to the commitment and vision of Rockstar Games. What began as an engine for arcade games has evolved to become one of the most powerful and advanced tools in the industry, and with GTA 6, it is about to redefine what is possible in the world of video games.
