Currently on my first playthrough myself, in Part 2 & 50 hours into it. I chose to go with the Black Eagles...
And I have no idea if I'm going down a good or evil route. I may have slipped on a banana and accidentally killed an important character... Or maybe two? Ah, who's counting when there's enemies to slay.
Edit: Finished the game that next morning. Pretty damn good game IMO. Next up is trying to get the rest of the endings, but with the Expansion Pass and Amiibo's. Goodbye another 180+ hrs lol.
Going to go the complete evil route this time, attempting it blind though so... IDK, everybody dies lol.
