It's Red Dead Redemption. What else is there to say that hasn't been said? The very moment when games as art started to show widespread value rather than a niche, as this presumed action Western proved itself to have a more internal and melancholy struggle through antihero John Marston.

RDR2 built on it with an even greater protagonist, but I'm unsure if it'll carry the same overall impact as the predecessor. Even Rockstar's game design that gets in the way of itself isn't an issue here. Its scantness and feeling of loneliness propells it into something special that few AAA games have understood.
