Red Dead Redemption 2 is a long game that’s renowned for its story and well-written characters, particularly the protagonist Arthur Morgan. As Arthur, players can choose to sink further and further into selfish villainy or turn a new leaf as the story progresses, trying to redeem themselves as Arthur slowly dies due to tuberculosis. It’s a beautiful and tragic tale either way, continuing themes from the first game about the human capability for change and the conflict between freedom and industrialization.
