Assassin's Creed
Originating as sequel idea for Prince of Persia: The Sands of Time, Assassin's Creed marked a massive move forward for developer Ubisoft into open world games. Many steps were taken as the game slowly developed into its own property, but the final product (and everything is has since spawned) are clear evidence that the right decisions were made. With sequels that cover just about every historical era, and a storyline that would even confuse Kingdom Hearts fans, Assassin's Creed holds a very special place in many gamers hearts. The franchise that keeps on giving, there is no end in sight and we love it.
