Overview

EA Pacific was a video-game development studio based in Irvine, California, whose organizational history passed through several owners and names before it became part of Electronic Arts. The studio began in 1986 as an internal American development division of Mastertronic. It subsequently operated within the North American structure of Virgin Games and Virgin Interactive, adopting the name Burst Studios in 1995. Following Electronic Arts' acquisition of Westwood Studios and Virgin Interactive's North American publishing operations in August 1998, the development group was renamed Westwood Pacific and later became EA Pacific. The studio was closely associated with the real-time strategy expertise inherited from the Westwood organization. Under the Westwood Pacific and EA Pacific names, it developed or co-developed titles including Nox and Command & Conquer: Red Alert 2. Its personnel and technical heritage also contributed to Command & Conquer: Generals, a major project that was completed under EA Los Angeles after the organizational transition. Some employees who had worked on earlier Westwood productions remained involved in later Command & Conquer projects, helping preserve continuity between the original Westwood development culture and Electronic Arts' subsequent Los Angeles-based strategy group. EA Pacific also played an important role in the development of the Strategy Action Game Engine, commonly known as SAGE. Electronic Arts began work on the engine in 2001, building it from Westwood Studios' W3D technology, which itself had been substantially derived from the SurRender 3D engine created by Hybrid Graphics. SAGE supported dynamic lighting, shadows, reflections, enhanced visual effects, and a stop-motion camera feature. Command & Conquer: Generals was the first game to use the engine. Later EA Los Angeles titles, including additional Command & Conquer games and The Lord of the Rings: The Battle for Middle-earth series, extended the technology. The engine was substantially revised for later console-capable releases, while RNA referred specifically to a later renderer rather than to the entire engine. The studio's corporate life ended in 2003, when EA Pacific was absorbed into EA Los Angeles. The closure was part of Electronic Arts' consolidation of its strategy-game development resources rather than the disappearance of the underlying technology or creative team. A number of former employees later joined Petroglyph Games, a company founded by veterans of Westwood and related strategy-game development operations. EA Pacific is therefore best understood as a transitional studio in the lineage connecting Mastertronic, Virgin Interactive, Westwood, Electronic Arts, and the later EA Los Angeles strategy portfolio.

History

EA Pacific's history began in 1986, when an American development division was established as a subsidiary of Mastertronic. Randall Masteller was the first programmer hired at the studio. The team later recruited additional development personnel, including individuals associated with the emerging Virgin development organization. Among the people connected with this period were Graeme Devine, Darren Bartlett, David Perry, and John Botti, although the studio's identity and ownership changed repeatedly as the business moved through the Mastertronic and Virgin corporate structures. In 1995, the development division adopted the name Burst Studios, reportedly following a recommendation from producer Neil Young. The studio experienced production difficulties during its early Burst period. Virgin Interactive president of worldwide publishing Brett W. Sperry later characterized the organizational model as sound in principle but unsuccessful at consistently delivering finished products. This period illustrates the operational challenges faced by internal development groups working within larger publishing organizations. A major change came in August 1998, when Electronic Arts acquired Westwood Studios and Virgin Interactive's North American publishing operations. The studio became Westwood Pacific and retained connections to the Westwood strategy-game tradition. Under that name it developed or co-developed Nox and Command & Conquer: Red Alert 2. Some Westwood employees continued working at the facility, including staff with experience on earlier Command & Conquer games. The studio was later renamed EA Pacific. EA Pacific's most important technical contribution was its work on the Strategy Action Game Engine, or SAGE. Electronic Arts began developing SAGE in 2001 from Westwood Studios' W3D technology. W3D had itself been a major modification of the SurRender 3D engine developed by Hybrid Graphics and had been used in Westwood projects such as Command & Conquer: Renegade and Earth & Beyond. SAGE introduced more advanced real-time lighting, object shadows and reflections, improved visual effects, and a stop-motion camera feature. Command & Conquer: Generals was the first game to use the engine, although development was completed by EA Los Angeles during the transition between studio organizations. EA Los Angeles continued to use and revise SAGE for later Command & Conquer releases and for The Lord of the Rings: The Battle for Middle-earth games. Later versions received substantial architectural changes, including PlayStation 3 support, renderer improvements associated with RNA, dynamic environmental music, and other internal upgrades. RNA was the name of a renderer rather than the name of a wholly separate replacement engine. SAGE remained in use through Command & Conquer 4: Tiberian Twilight. In 2003, EA Pacific was absorbed into EA Los Angeles and ceased to operate as an independent studio. Some former employees subsequently joined Petroglyph Games, linking the studio's personnel history to later independent real-time strategy development. EA Pacific's legacy consequently rests less on a long-lived standalone brand than on its role in the transfer of Westwood and Virgin development capabilities into Electronic Arts' Los Angeles strategy organization.
