The shooting is pretty good on MGSV though?
Edit: snd MGSV feels weighty without having to spam A button to run lol
Weapon handling, etc. Are good, but when the bullets touch the enemies, it's nowhere near what games with euphoria engine do in term of dynamic reactions, ragdoll etc, also mgs5 is one game in a saga of 6 games, it's not out of this world to say that nobody play mgs games for the pure shooting.
It is not perfect and sometimes animations can glitch but that is the price to pay for using non-precanned animations, they look much better when they work, much silly when they don't, but you are never going to see something remotely similar to these 2 videos when you shoot enemies on mgs5.
Shot some enemies on mgs5 and they are all fall down the same with the same hit reactions etc, after you kill 20 enemies you already saw everytning but you can shot 100.000 enemies in rdr2 and never quite see the same exact death, they have different strenghts.
Gunplay is such a broad term that include both everything that happen before shooting and what happen when the bullets touch the enemies, some games have a great first part but a shitty second one, rdr2 may have a shitty aim system and a shitty cover system (they feel better on pc tho) but when bullets touch the enemies, i consider this part order of magnitude better than mgs5 unless you really love arcadey, samey feeling and not something that can glitch sometimes but it is way more dynamic and violent.
There is a reason why games with euphoria have the highest count of kill compilations on youtube, it is not a coincidence jist because they sell a lot, people love to see the enemy reaction to getting shoot , especially in mp3 and rdr1-2 that imo have better shooting than gta4-5 (non-modded)
But like i said, gunplay is such a broad term and ,any people care more about the first part than the second part, i'm the opposite, perfect weapon handling is nothing without good hit reaction, dynamic animations, marks on enemies, gore and ragdoll to sell the impacts.
P.s. why do you bring movements in a discussion about gunplay?
P.p.s. pretty sure rdr2 had the option to put sprint on l3 without tapping A.
