I know exactly what you mean and I agree completely
everything from the way you move and aim just feels so incredibly smooth
personally I don't care much for the gore as it's a small detail and I can see why they left it out of an open world game like gta 5 to focus on other things.
but the movement and aiming would have been perfect for gta 5
RDR is an open world R* game and it has shoulder switch and crouching. The "it's GTA that's why it's not there" argument doesn't hold water.
It's GTA, the star franchise, it should be the very best that R* can do.
there's open world and there's open world
you can't really compare a huge flat desert with a few coyotes and deer to a sprawling city filled to the brim with npc's and traffic.
gta 5 having to skip out on some of the graphical details makes sense
I mean it's not like you can say this game looks bad, definitely no worse than RDR
