This sink ain't big enough
Just like GTA4, I got 4/5's through the story then just said "fuck it". You can only do the same repetitive tasks over and over before you get turned off and don't want to come back. Especially when the shooting mechanics make shooting enemies comparable to spreading butter on toast.
"BUT THE STORRYYYY" you'll cry. Marston is/was a an outlaw who needs to find his former outlaws-in-arms and make up for his past. He tells you this plenty of times over long, drawn out horse rides that - more often than they should - be longer than the actual dialogue. Rockstar Games have some of the most authentic voice acting and writing in their games. They might have recycled characters (Marston = Niko) with some details changed, or just turn stereotypes into secondary, comic relief type characters (Irish, that gay guy in GTA4) but at least Rockstar knows how to work with these troped-to-fuck characters.
"BUT THERE'S SO MUCH TO DO!!!" you'll also cry. Gambling is fun, that's true. Hunting however, gets old fast. Contracts get old, random miniquests in town are kinda exciting but even they get old.
The game's really nice looking, but there are a lot of graphical bugs which makes things disappear, and that got downright annoying.
So you might write this review off as a guy who clearly just didn't finish the game. But the point is, I didn't feel compelled to. I heard the ending's sick n all, but what can I say? The monotonously old Rockstar gameplay and story formula is just too last gen.
