A lot of people are saying Horizon has the advantage of being very unique, and I agree, but let's remember that when Horizon came out it had a lot of publicity against Breath of the Wild. When you have a comparison that has been as overused as Breath of the Wild and Horizon, naturally one of those games is going to come out looking "less unique". There were even a lot of fanboys arguing Horizon wasn't a unique product at all. I do think more people look at Horizon as a unique product compared to Days Gone, simply because Robot Dinosaurs haven't been capitalized on as much as Zombies as a concept. But still, Horizon did get some shit slung at it too.
