I'm a big fan of RDR2 (~470hrs from two full playthroughs), and would recommend it to anyone, even if they don't normally play games. However I can understand why it might not appeal to some people, for one reason or another.

I suspect this might be because of a slow start to the story - frequently the game falls victim to its own 'cinematicism' and holds the player's hand too much (e.g. walking too far away from a mission area or trying things outside of the box runs the risk of failing the mission, unlike the creative approaches one may take in Rockstar's earlier adventures). I have stopped seeing RDR2 as a 'game', and instead treat it as a world to experience, kind of like a good book. I want to feel that world more than conventionally play in it, and this process greatly heightens my attachment to it as well as to Arthur, increasing immersion.

That being said, I probably speak for many when I hope that you get to finish that journey someday and feel your place within it. It might take as long as it needs to, but it might just be worth it.
