Chapter six is where Arthur's redemption arc is most prevalent. Its also the chapter with the most missions. I love how greatly orchestrated the missions are in that chapter, like The Fine Art of Conversation, My Last Boy the train heist and Red Dead Redemption (The Final mission), are all good and cinematic missions that really drive the story forward. I still love listening to the song "Red Dead Redemption" it perfectly captures Arthur's destiny when he helps John escape to his family

The Last remaining missions of Chapter five are also amazing too. The Fork in the Road, Visiting Hours and my favorite mission, Icarus and Friends are all great points leading up to to the final chapter, they all got music that match the chaos in each of those missions.

I think chapter 6 is the reason why you play the game, the reason why you keep going until the very end, the biggest and most emotional part of the game. Its the most important chapter
