I’ll chime in! This is absolutely true in my experience. I loved RDR1 (still one of my favorite games) but with RDR2, I felt exactly the same as you. Too much fishing, hunting, and other distracting elements. RDR1 has some of that but it’s on a much smaller and easier to complete scale. I never finished the second one, about halfway through, I went back and replayed the first.
That’s basically been Rockstar’s MO since GTA4. I enjoyed GTA3 through San Andreas but GTA4 felt like bowling with cousin Roman more than a GTA game.
I’ll agree that RDR is different in a many ways, it’s still Rockstar so some of the gameplay is similar but a lot more fun with the western vibe over the city. And while I enjoyed some of the GTA games, none of them come close to RDR1 in my opinion. I just brought GTA up because I saw the same life sim crap creeping in there around GTA4 like I did RDR2
