Favorite loyalty mission
But they're all so good!
Okay, I'm not wild about Grunt's, but even that is saved by having an awesome reunion with Wrex. But really, though each loyalty mission is different in terms of the gameplay style, the amount of combat, and how much Shepard actually has to do, they're all quite emotionally engaging. Shep has to make some tough decisions- or encourage others to do so- as her companions sort out shit from their pasts in order to better focus on the present.
I love Samara's, wherein you accompany her to Omega so she can find and kill her daughter Morinth. Shepard working his/her way through the nightclub to draw Morinth's attention is hilarious, from punching out a lecherous turian to this:
(seriously, "I do wanna think that!" makes me laugh out loud every damn time I hear it)
Then, if you successfully arouse Morinth's interest, there's the BAMF showdown between her and her Justicar mother, which culminates in Shepard choosing which one will die.
Great stuff! But my favorite? My favorite, I think, is Tali's.
Visit the quarian flotilla, get all And Justice for All as you defend your bestie against bogus treason charges, and kill a shit ton of geth...yes please. There's tough combat. It greatly develops Tali's character and her relationship with Shepard. You help steer the course of the frickin' galaxy as you advise the quarians as they consider all-out war with the geth. And you get to hear voice work by Claudia Black in the role of Admiral Xen. Ain't nothin' not to love here!
You know, I just thought- why don't the quarians have clear face masks? Would it make a difference to them? At least they could see each other, geez. I know it's a conceit for the game to make 'em more mysterious and all, but in their universe, what the heck?
Also, for some reason, I thought maybe quarians do this so they can make out with each other (or Shepard) easier:
Also, I'm very very tired.
