Vivendi Games, formerly known as Vivendi Universal Games, was the holdings company for Sierra Entertainment and Blizzard Entertainment. Vivendi Games was founded as Vivendi Universal Games after Vivendi bought Universal Studios in the early 2000s. Before then, Vivendi Universal Games was known as Universal Interactive Studios.

Vivendi Games was a 100% subsidiary of Vivendi S.A.. Headed by Bruce Hack, it was headquartered in Los Angeles, California and employed over 3,400 people at 4 separate development divisions. Vivendi Games owned the rights to such popular franchises as Warcraft, StarCraft, Diablo and World of Warcraft (all games developed by Blizzard Entertainment) as well as others like Empire Earth, Leisure Suit Larry, Ground Control, Tribes, Crash Bandicoot and Spyro the Dragon owned by Sierra Entertainment. It is now merged with Activision and is known as Activision Blizzard.

The history of Vivendi Games begins in February 1996, when CUC International, a large mail order and subscription company, offered to acquire entertainment software developer Sierra Entertainment. Headquartered in Bellevue, Washington, Sierra was the leading developer and publisher of computer games and was famous for its adventure game series such as King's Quest, Gabriel Knight, Space Quest, and Leisure Suit Larry. Sierra was a public company, which employed roughly 1,000 employees at 12 different acquired studios. CUC offered to absorb Sierra's stock shares at a price roughly 90% higher than what Sierra was trading, and on July 24, 1996, Sierra became a wholly owned subsidiary of CUC.
