#1 Rodrigo Borgia – Assassin’s Creed II
Players were easily itching to get at Rodrigo Borgia, head of the Templars and singlehandedly the person responsible for the death of Ezio Auditore’s family. So when it came time to actually use all of the skills and traits that you’ve learned throughout the game, developers instead have players go against Rodrigo Borgia in a fist fight. No special weapons or skills that you’ve picked up from being an assassin, instead it's full-on brawler mode. This boss battle is one that still gets talked about to this day as just an overall lame and boring battle.
