Honestly, this is just one more of the indicators that AAA development budgets have gotten way too large. I love when devs put care into their art, but it should be somewhere it matters. I can count the number of times I noticed my horses testicles retracting on my knee. It's just a waste of money.
In Dwarf Fortress, for example, when detail is added and actually relevant, it's great. We need more of this, where useful additions are done to create a more tactile world. When time and money are spent doing stuff like the testicles in RDR2, I just imagine how that could have been spent on a different game, instead of just inflating an already massively expensive game and adding essentially nothing, except something for people to post about online.
