I'm a bit late with this but I want to thank the team from the bottom of my heart for making the Citadel DLC an experience that truly rewards players no matter if they romance the popular LI or not. I loved seeing Kaidan show up in the initial sequence, and for my singleShep Liara and Vega/Wrex was a good choice.
Besides the integration of Shepard's LI, I also loved how my class was reflected in-game. I finally got to talk to people about my biotics! And they referred to me as one!
The mix of difficult battle, the stealthy heist and the boss fight at the end made the Citadel one of my most memorable ME-experiences gameplay-wise. The different mix of tempo and intensity was great, and having my whole crew with me while going into the archives was a great idea!
I thought the inclusion of clone!Shepard was ridiculous, but it was the right kind of ridiculous! My Shepard has a pony-tail, which hardly any other NPC has in the game, so I actually realized a moment before the revelation whom I was dealing with, hehe. Anyways, it was completely over-the-top and therefore totally awesome!
Another great aspect with this DLC was to see my Shepard cut loose a little and join in the fun with great banter. The Enemy barks, Shepard's fixation on irrelevant detals ("I don't really sound like that, do I?" and the all-mighty Space Hamster!) was so funny to me! The comedic timing was good, and I think Samantha stole the whole DLC with her tooth brush.
The boss fight was difficult, but in a fun way. It got a bit uncoordinated, but I wouldn't expect a fight with my own clone to be a "good, clean fight", it got itty-gritty, all-rules-are-off, just the way it should. The initial stealthy part with no medi-gel was a nightmare though!
I loved the party, and have replayed it so many times to try to get all the different variations of the banter. All the different meet-ups in the Party district was also a lot of fun. I also enjoy the Armax Arena, though I haven't unlocked the bonus armour yet.
I'd like to give a special thanks for Thane's memorial and video messages. This was exactly what I felt that my Shepard, who lost her lover, needed to be able to process her loss. It was a lovely scene and one that went straight to my heart. I also loved that she sort of got to hear him before returning to the Normandy, since other Shepards got to talk to their LI. Very nicely done!
There was a few problematic scenes in the DLC, but on the whole it felt a lot more "complete" than the rest of the game (and I say that as someone who loved the game, original endings and all). It makes me very hopeful for your upcoming projects!
I hope that Bioware will continue to strive to make all gamers feel equal, male or female, straight or gay. And as always, that you will keep doing amazing games and add-ons like ME3, Leviathan, Omega, From Ashes and the Citadel!
