That "self-seriousness" is, in my opinion, one of the most effective criticisms of Mass Effect 3, a game that effectively worked to tie up many of the storylines from the first two games of the series, but did so via an increasingly dramatic series of violent confrontations. This often worked to create propulsive stories, particularly the fantastic sequence on Tuchanka. But it also felt more generally like there was just too much grim warfare. Of course, the game believing its own mythology to be its most important aspect led to the controversial ending that embodied the game world's internal logic of Shepard-versus-the-Reapers.
This component of Mass Effect exists in 'Citadel' as the first half of the new content. In it, Shepard is ordered to the Citadel for repairs to the Normandy as well as a bit of relaxation. Something goes wrong, there's a conspiracy against her (or his) life, and Shepard is forced to save the day again. The story is notably lighter than anything in Mass Effect 3's primary narrative, and it's somewhat detached from the overarching Reaper war. Indeed, it feels more like one of Mass Effect 2's character quests: In a way, Citadel is Commander Shepard's loyalty mission. In terms of gameplay, Citadel adds new weapons and a compelling boss encounter. The shooting section of 'Citadel' can be trifling, but it doesn't overstay its welcome.
For many players, the joy of the series comes not from being in Mass Effect, but rather playing with Mass Effect. These players see the game in terms of how it reacts to what they did, and want to see how those parts interact based on the decisions made throughout the trilogy. They delight in seeing, for example, that if Garrus and Tali are alive, and missing romance in their lives, those crazy kids hook up in Mass Effect 3
. These are the players for which the second part of 'Citadel' was created, where you wander around the new parts of the Citadel and talk to your old friends.
BioWare's primary strength through its history has been its characterization. From Minsc and HK-47 to Aveline and Garrus, the characters are usually the most memorable parts of their games (though not always positively, looking at you Ashley & Carth.) There's much more to the games, to be certain, but it's the characters, their relationships, and their interactions, that stand out the most.
After the shooting is complete, Citadel focused on nothing but characterization. Shepard has a new apartment, and can hang out with familiar friends, or perhaps the Commander can go into a new section of the Citadel and hang out with crew members there. So you'll have the chance to try watch movies with Tali, watch sports with James and Cortez, or have a relaxed chat with Miranda. These segments are moderately fun, but can feel a little bit stilted especially when completed all at once.
The main event, the part that should delight people invested in the varieties of character interactions, is a massive party that Shepard throws in her (or his!) new apartment. Shepard can invite every previous surviving party member and watch them interact. It's almost like the squad members are toys as part of a diorama. It leads to a host of entertaining interactions, such as EDI trying to convince Joker to dance, or Grunt and Wrex arguing over who's tougher.
The party is a massive success in terms of acknowledging that the characters of Mass Effect are its most important component for a large number of fans that it's tempting to call it a perfect send-off for the trilogy. But it actually occupies a strange space where it's only a goodbye for some. I simply loaded one of my late saved games, played Citadel, and was done with it and the single-player mode of the game until my next replay. But on that replay for me, and for many people playing the first time, Citadel will be integrated with the rest of the game. I can't tell if this will work as well. I can see the Citadel conversations being even better if you space them out instead of playing them all at once, but I could also see aspects of the add-on fitting in poorly with the rest of the grim, propulsive Mass Effect 3
Yet I think I actually like not being able to judge how Citadel integrates with the main game. More than most games, Mass Effect is a subjective experience, built around who Shepard is, what Shepard has decided, and who's still alive. To play Citadel, especially the party section, is to be immersed in that subjectivity. It's a scene that shouldn't stick out too much to fans of Mass Effect as a serious story. But to those of us who played for the glorious mess of watching how different characters responded to slightly different events, who found the crew of the Normandy the best part of Mass Effect, it's a love letter. Citadel demonstrates that yes, BioWare did understand what made their game special, for all kinds of different players.
