Over the years, several video games in the Command & Conquer franchise began development, but were eventually canceled. Command & Conquer: Renegade 2 and Command & Conquer: Continuum were both in development by Westwood Studios before being canceled due to Electronic Arts' closure of Westwood Studios in 2003. Tiberian Incursion, the sequel to Tiberian Sun was also in early stages of development, but was put on hold until some of its concepts were reused in Tiberium Wars. Tiberium was being developed by EA Los Angeles before it was canceled due to quality concerns.
