Strategy Action Game Engine

The Strategy Action Game Engine, abbreviated SAGE, is a game engine used for the development of 3D video games by Electronic Arts Pacific and Electronic Arts Los Angeles. Its first iteration uses the rendering technology of Westwood's W3D engine.Skaggs, Mark (16 March 2002). . GameSpot. Retrieved 26 March 2002.

Mark Skaggs led the team working on Generals at EA Pacific that would create the SAGE engine. Work on the 3D engine began in January 2001 as they hit limits with the engine they were using for the development of Yuri's Revenge. They considered the Quake engine, Unreal Engine and LithTech, but decided in March 2001 that they would use Westwood 3D's rendering technology from Renegade as the basis for their new engine and built further upon that basis to add all other elements.
The new engine would allow for "more cinematic possibilities during missions, giving the designers the freedom they needed to tell rich in-game stories with dramatic Hollywood moments". It allowed for dynamic lighting that would cast realistic shadows and reflections onto most objects as well as higher quality visual effects. One of the issues the developers battled with during the development of the engine was how to allow the player to place buildings on unleveled 3D terrain without it looking like the building was sitting on a rubber mat, which was solved within a few weeks of work.
