What is the name of Ezio Auditore's first Assassin's Creed game?

Ezio Auditore first appears as the protagonist of Assassin's Creed II.

Ubisoft released Assassin's Creed II in 2009 as the direct sequel to the 2007 original. Its story begins in Renaissance Italy and follows Ezio from his youth in Florence through his transformation into an Assassin. Important locations include Florence, Venice, Monteriggioni, and Forlì.

The game expanded the original formula with economic management, improved climbing, new weapons, and a broader set of activities. Ezio's personal story is tied to the murder of his family and his discovery of a larger conflict involving the Templars and ancient precursor artifacts.

Brotherhood and Revelations are not alternate names for the second game. They are later entries that continue Ezio's story: Brotherhood focuses heavily on Rome, while Revelations follows Ezio in Constantinople. Assassin's Creed II also begins the Ezio trilogy, which became one of the best-known character arcs in the series.
