What can I say that hasn't been said and that you don't know.
This game is IN-SANE.
The attention to detail is mind-boggling, the missions, from the smallest to all the main missions are worthy of oscars.
The single player campaign is one of the best adventures I ever went on in my life. This is why I love games.
The beauty of this game in indescribable. It's one of most realistic living worlds I've ever been in.
In fact, it felt so real to me, that I would spend hours living and breathing the game, I felt I was there, at that time.
Taking care of my horse, spending time fishing and hunting, sometimes for hours.
Riding my horse in strong winds, and heavy rain, collecting every piece of clothing and trying to look dashing at all times.
I got attached to people, took care of them, or dragged them behind my horse when I wasn't in the mood for their BS.
I've been there. I lived there. That was me, I was a cowboy. Nobody will convince me otherwise.
