At this point, Lévy replaced René Penisson as chairman of Activision Blizzard. The merger was completed on July 10. While Blizzard retained its autonomy and corporate leadership in the merger, other Vivendi Games divisions such as Sierra ceased operation. With the merger, Kotick was quoted stating if a Sierra product did not meet Activision's requirements, they "won't likely be retained." Some of these games ultimately were published by other studios, including Ghostbusters: The Video Game, Brütal Legend, The Chronicles of Riddick: Assault on Dark Athena, and 50 Cent: Blood on the Sand. However, a number of Sierra's games such as Crash Bandicoot, Spyro, and Prototype were retained and are now published by Activision.
