I love the Assassin's Creed series made by Ubisoft. It combines stealth exploration with fluid melee combat, and across the franchise, has been set in various historical periods complete with various famous historical figures. And underlying it all is multi-layered lore involving the secret history of the world-- on one level, the conflict between the Brotherhood of Assassins and the Templar Order, and on another, the lingering influence of a precursor race, the 'First Civilization,' who were responsible for creating mankind in the first place. It explores themes such as free will and security, with the Assassins seeking to safeguard the former and the Templars trying to assure the latter, usually impacting the former.
The most recent entry to the franchise, Assassin's Creed Origins, rewinds things back to Egypt during the time of Cleopatra and Julius Caesar, and shows us how the Brotherhood of Assassins was born. It incorporated a lot more RPG-style elements and was more open-world, almost Skyrim-esque in how you could explore the map to find more locations across Egypt.
But where does the Creed go from here?
