As I was playing Red Dead Redemption today, I happened across a woman crying beside a dead man. By his limp hand was a revolver. The game only gives players a short amount of time to respond to strangers in need. It seemed I had missed my opportunity to help this man fight off bandits. He had failed to defend himself and died.
I stood for a few seconds watching the woman cry, and I turned away. Then I heard a gunshot. I spun back around, thinking it was a trick (like previous ploys NPCs had used on me) -- the woman must have killed the man and then pretended to be grieving so I would let down my guard. But no, the woman was dead. She had indeed been grieving, and now she had committed suicide with her fallen husband's revolver.
Kudos to Rockstar for creating a very memorable game-story experience.
