What is the name of the first Assassin's Creed game directed by Patrice Désilets?

Assassin's Creed is the first Assassin's Creed game directed by Patrice Désilets.

Désilets served as creative director on the original game, which Ubisoft Montreal developed and Ubisoft released in 2007. His work helped shape the series' early design, including its historical settings, parkour movement, social stealth, and layered modern-day narrative.

Before Assassin's Creed, Désilets worked on games in Ubisoft's Prince of Persia series, including The Sands of Time. The Assassin project began as a Prince of Persia-related concept before developing into a separate franchise.

Désilets later worked on Assassin's Creed II, but the original game is the specific answer when asking which title he first directed in the series. His later career included the creation of the independent game Ancestors: The Humankind Odyssey.
