The document discusses the history and development of the Assassin's Creed franchise. It began as a spin-off of Prince of Persia but was rebranded as its own IP. The franchise found major success with Assassin's Creed II and its sequels that followed Ezio's story. Later games introduced new characters and time periods but continued expanding gameplay elements and story. While sales remained strong, later games like Unity and Syndicate received criticism for bugs that hurt initial sales figures. Overall the franchise has grown tremendously from its origins to become one of Ubisoft's most successful.
