Combat is expressive. You can tell a lot about a character based on the way that he fights. I wrote about this idea some time ago regarding Assassin’s Creed. I considered how the fighting styles of Altair and Ezio changed over time and how those changes reflected on each character.
In retrospect, I wrote that piece based on an assumption that went unspoken at the time. Combat is at its most expressive when it changes. Seeing Ezio’s techniques, arsenal, and skills evolve over the course of three games was far more interesting than simply analyzing Altair based on one game.
