I already have RDR2 and I barely play it
Would you say it's due more to the setting of the game or the actual gameplay itself?
My issue with RDR2 is basically the game forces you to use 3rd person view in order to win gunfights while relying on autoaim. If you try to first person the whole game, eventually you will lose to almost every bounty hunter encounter because they can kill you in 2 seconds flat, and there's no humanly way possible to take them out with manual aim using a mouse in the same timespan.
Some of us simply do not like 3rd person _at all_ when gunplay is involved.
