I think rdr2 is a great evolution in RPG types games. You're actually forced to think as Arthur would think. My favorite version of Arthur is borderline morally ambiguous. Deep down he's a good man with a clearly defined moral code. When push comes to shove he'll do the right thing, however he'd also rob and kill in line with that ambiguous morality. And you're force to reject modern sentimentality. Rdr's world is hard and cruel world. A kill or be killed world. But it's also about mankind establishing communities.
