Finished Chapter 6, and man, it was heavy. Haven't really done much in the Epilogue yet cuz I honestly needed to step away and process it for a bit. I even got the "good" ending, too.
SPOILERS BELOW
I think Arthur may be one of, if not, the best protagonist Rockstar has written. I feel like I played the game pretty accurately to how his character unfolded, in that I was kinda ruthless early on, but as the story progressed I made softer more honor-driven decisions. And this was prior to knowing how it would end. But even if you didn't play this way, Arthur felt very mulit-dimensional as a person, which is something I feel a lot of Rockstar characters lack. My heart honestly sank to my stomach as his last mission unfolded, especially as he gave a tearful "thank you" to his dying horse, of whom I used from the moment I got him up until the very end. It can't be overstated how much this game makes you care about the characters you watch, and how much it makes you feel for them when tragedy strikes. What an experience, and I'm not even done yet.
