All the Assassin's Creed games, ranked

You play as Templars (the antagonists of the series) who are training by using the Animus, learning how to hunt and kill assassins, which is a neat twist. It's a game of cat and mouse: you're given a target to track and kill while other players are hunt you as well. The premise is so unique, and so satisfyingly tense. I can't think of any other multiplayer experience that put so many resources into building a compelling stealth experience to play with friends. I loved being able to sneak up to a target and poison them silently, then watch them collapse like a rag doll moments later.
