Most realized open populated world ever.
Most realised atmosphere of a slice of time in a video game.
Best horse testicles in a video game, by far.
...there's 3 for you.
Its not as blatantly cut and paste as say AC Odyssey but I already saw repeating stranger missions all around me, the stagecoach, train and store robberies and hunts are all the same, and I dont think dinosaur bones, treasure maps and cigarette card collections are worthy of any mention
I've only encountered 2-3 repeating things in my 50 hours so far, compare it with any other open world....then come back to me with a more non-repetitive 50 hours anywhere else in open world gaming (if you can, kudos though, happy to be proved wrong).
