I'm now 10 hours in, and actually enjoying it more and more it seems lol.
A few things that have helped in a big way increase the enjoyment so far, new monitor, the OLED absolutely makes a difference especially at night! And the new GPU. Whilst my 2070 Super was able to lock 60fps at 3440x1440 max settings, I now have the game locked at 120fps (144Hz gsync, vsync is off) - no preset framerate lock option for 144 fps in the game it seems but whatevs. 120 fps feels so much more responsive and smoother than 60 that I used to have before on the 60Hz ultrawide.
I actually bought the game on 18th May 2021, so have had it for over a year and only just now put 10 hours into it. I played RDR2 and many others in that time of course but would say I enjoy this more than the yawnfest that I felt RDR2 ended up being purely because the land is so vast and the things to do are so far apart that you end up wading back and forth endlessly.
Horizon Zero Dawn is another I tried to get back into but after several hours again just had to leave it as just wasn't pulling me in even though it too looks amazing and is very smooth/bug-free.
I should have the game changing weapon soon too so I've heard that changes the gameplay dynamic somewhat. Looking forward to that.
