Have made it to chapter 4 and whilst only maybe playing a couple of times a week, I’m still hugely enjoying it. I dip into the storyline missions from time to time, but for the most part am very happy doing my own thing. For a map that I thought I’d explored in detail, it’s amazing how many things I’m still discovering - managed to miss a train wreck on my first couple of laps so only stumbled on that in the last week, then had fun trying to find out if I could get into it.
Am a big fan of the trapper and the horrendous clothes he can craft so have spent a ridiculous amount of time hunting - get some pretty funny comments about my outfits when I hit town. Also like the fact that the world has been changing over time - those guys building the house near Valentine have finished 
Still haven’t dragged someone 3000m or whatever with the lasso though.
