I finished Mass Effect 3's Citadel DLC and, well, it was... nice. I mean, it wasn't bad. It had some decent action, and the character interactions were good to see. It was clearly a love letter to the fans, but... that's really all it was. There was no epic adventure like we had in Lair of the Shadow Broker (still the king of Mass Effect DLCs in my opinion), nor was there an interesting story like we had in Leviathan and Overlord. To me, Citadel's story was about as deep as your average Saturday morning cartoon, and the action portion was over far too quickly for my liking. And hey, I recognize that the shallowness of the story and the characters may have been intentional if the focus was to be jokes and endearing interactions among the crew. But the problem for me is that this DLC cost 1200 points when, in my opinion, it probably should have been priced at 800.
When I got to the get-together segment of the DLC, I briefly thought that I was just at a halfway point and that we all might be going after the villain's accomplice after the festivities. In fact, I think it would have been neat if said accomplice had crashed the party. Imagine a shoot-out in Anderson's/Shepard's apartment. Sadly, I was actually at the end of the DLC.
Also, I was disappointed with the Citadel exploration. If any of you thought you might finally be able to jog around the aesthetically pleasing "outside" portion of the Citadel like you did in the original Mass Effect... nope. The new indoor portion of the Citadel you can explore after the fighting ends is pretty nice and features a couple of neat things to check out (like the combat simulator), but it would have been great to be able to run around "outside" again.
Because of its extremely relevant Mass Effect universe story, Leviathan has ended up being my favorite Mass Effect 3 DLC. Omega was a fun action romp, but it wasn't quite the Shadow Broker successor I had been hoping for. From Ashes was little more than a character introduction. And you've presumably just read my thoughts on Citadel.
