Which game is the first entry in Assassin's Creed's Ezio trilogy?

Assassin's Creed II is the first entry in Assassin's Creed's Ezio trilogy. Ubisoft released the game in November 2009 for the PlayStation 3 and Xbox 360, followed by a Windows release in March 2010.

The story follows Ezio Auditore da Firenze, a young Florentine nobleman who becomes involved in the Assassin-Templar conflict after a family tragedy. Its historical setting spans Renaissance Italy, with major locations including Florence, Venice, and Monteriggioni.

The two direct sequels are Assassin's Creed: Brotherhood and Assassin's Creed: Revelations. Brotherhood continues Ezio's story mainly in Rome, while Revelations brings him to Constantinople and also revisits Altaïr's life.

Assassin's Creed II expanded substantially on the first game with additional weapons, economic systems, and exploration features. It is therefore distinct from Brotherhood, despite all three games forming one connected Ezio narrative.
