You are missing all of the best ones. Poll irrelevant. From best to worst (gameplay-wise): [spoiler] AC:brotherhood AC2 AC AC: black flag AC: revelations AC3 AC unity[/spoiler] Story wise: [spoiler] AC2 AC:brotherhood AC: revelations AC: black flag AC AC3 AC: unity [/spoiler] My favorite was probably either brotherhood or 4. Brotherhood improved a bit on 2 with mechanics and the story was on par. Black flag was a very fun game, a good refresher after the boring story of 3 (or rather the boring character Connor). Swordplay wasn't the best but I loved the changes that Edward went through and how he had to come to terms with his problems instead of escaping them through indulgences and adventure Plus, freed cry was probably my favorite AC DLC I've ever played, right above the da Vinci one from brotherhood.
