I’m not a fan of the LotE outfit, although I love the vest with its chain and star. I got it for Arthur in chapter 3 and I use the vest in his custom outfit but ditch the stripy pants and the red jacket.
I’ve 100%’d the game, and seen every point of interest, completed every compendium item etc but I haven’t done the gold rush. That is just too tedious, sitting through all the riding before a replay just takes too long.
