Summary: This review contains spoilers, click expand to view. Citadel is a very good DLC but Bioware should have taken a piece of humble pie and made this a post ending DLC. From the beginning, It basically sets itself out to be one last hoorah with your squad-mates and its basically just that.
Summary: Remember all those squadmates that you wish you could have had by your side in Mass Effect 3? The Citadel DLC allows all/most of your old allies to return, and with little mention of the dark Reaper war raging on, the tone of this is a lot different. It has a villain that you love to hate, and the party that you get to throw makes you wish that you could replay it over and over again.
Summary: The premise for this DLC was quite interesting: leave your normal team behind to go on an adventure with the morally ambiguous Aria. And the story itself is quite good, as there was interesting motivation and choices for a Paragon player to go through. However, the greatness of the Mass Effect universe is in its attention to detail and the creation of a world that feels alive and complex.
