Eh, I don't think that at all. RDR2 is definitely a good game, but it's really not that amazing. I don't think it does particularly anything new or exciting for open world games and for me the experience really started to drag after awhile, mostly for lots of little reasons related to traveling, animations, and the story. What it does best is generally the world experience, like it feels lived in and interconnected well and looks impressive on PS4 Pro.
Nearly done with the story myself as I basically hit a point around halfway through the game that I just got kinda tired of doing the side story stuff, it wasn't very engaging and didn't feel like I was getting much out of it, so I've mostly just been doing story missions myself.
