By the time 2013 rolled around, the Assassin's Creed franchise was in pretty dire straits.
What was once the most iconic and popular open world series in gaming had been put through the ringer, with the disappointment of Ezio and Altair's bow-outs in Revelations, and the frustrating technical bugs and confused storyline that plagued Assassin's Creed III.
Fans of the series and shareholders within Ubisoft were itching following III's noticeably poor reception, and the reveal that the next game in the series would be based around the early 1700s Golden Age of Piracy did very little to ease the community's concerns.
What followed all of this disappointment however, was one of the most breathtaking and impressive games Ubisoft has ever produced.
Assassin's Creed Black Flag was released in October 2013, selling over fifteen million copies, and should be regarded as the most ambitious and accomplished game in the entire history of Assassin's Creed.
From its awesome mechanics, huge and vibrant open world, memorable characters and clever tone, the game remains one of the most fun titles in the AC library, and continues to stand out to this day.
