What is the title of the 2009 Assassin's Creed game starring Ezio Auditore?

The 2009 Assassin's Creed game starring Ezio Auditore is Assassin's Creed II.

Assassin's Creed II was released in 2009 as the direct successor to the original 2007 game. It introduces Ezio Auditore da Firenze and follows his development from a young Florentine nobleman into a skilled Assassin across several decades of Renaissance Italy.

The campaign visits Florence, Monteriggioni, San Gimignano, Forlì, Venice, and the Vatican district of Rome. Its story features historical figures including Leonardo da Vinci, Lorenzo de' Medici, and Rodrigo Borgia, while remaining a fictional adventure.

Brotherhood continues Ezio's story and is mainly set in Rome. Revelations later follows an older Ezio in Constantinople, and Assassin's Creed III shifts the principal historical narrative to the American Revolution. Those titles are related but are not the game that first stars Ezio.
