Having finished the story, I can say Red Dead 2 is within my top 10 of all time. Love it. The core gameplay is sluggish for sure, but holy hell what an experience and I love all characters in their own regard. Rivals Naughty Dog and CD project in terms of writing in my opinion.
But I do have to rant a bit. In all my years of near broken PS3 ports (Bethesda games in particular), I have never encountered as many hampering bugs as in this game. People almost permenantly dissapearing from camp, sidequest that I cannot start, modified weapons dissapearing forever and now permanently losing ALL my weapons in the epilouge. In the former cases, I had a recent save to fix it, in case of the epilogue and losing all weapons, I'd have to redo 5 hours to hope getting them back. And I know a lot of people are missing people from the camp, namely Sadie, John, Abigail, and Jack in chapters 2 and 3. You'd think they have a patch by now.
So my advice is to keep saving seperately frequently and hope you don't have the same luck as me.
