Have it. Awesome game.
One thing I'd like to slap a developer across the face for: horses + water.
It's obvious that these guys are a bunch of asses who have never seen or ridden a horse.
Seriously? Water kills horses? Really?
No it doesn't.
Ours cross streams, walk in the shallow river we got here - no problem. ( The one I use in game - looks like one of ours.

) I don't know why they did what they did.
And a bonus here: horses can swim. Naw, really?
Yes really. *facepalm*
They also do come to a whistle.

Takes training though. And a shitload of treats.
For that minor defect, I shall give a negative 0.1. 9.9/10. Other than that, I think Rockstar has found a kinda neglected genre (western) that KICKS SOME HUGE FUCKING ASS! This is one pretty perfect game - if you don't have it, what's your problem? Get out there and get it.
