I picked up Mass Effect Legendary Edition; mostly for my daughter that never had a chance to play the originals, but I spent some time playing with it myself. It as interesting to be reminded that one of the original inspiration for LoM was Mass Effect 2, and speech at the end of the game. I tried to channel part of that for Act VI's opening (after Emily's unwanted vacation), but I wanted to take another stab at it.
MC will never go grim-dark; that's the wrong game, and the wrong characters for it; at his core he's neutral good, or at worst chaotic good. Part of that is Emily, who's pretty much pure lawful good (as opposed to Katie, who's more or less pure Chaotic Good), and part of that is just his personal character arc. But I do occasionally want to give the chaotic/neutral choices, and it's something I'm going to try to be more explicit with in Book 2. Usually there's three paths through situations like this, STR (chaotic), CHR (lawful/neutral) and INT (balanced path taken).
For the opening of Act VIII, and the discussion at the grand gathering, I made a few renderers to play based on what choices MC took... I liked them enough that I turned them into 1080p wallpapers for fun.
