It isn't too hard, but the damn thing takes way too long to balance. It would have been nice if taming a type of horse would make you a pro at it, therefore not needing to do it again, or just having it be a skill that could be leveled up. I've tamed at least 4 white horses and each time is like 30+ seconds of "left...right...left...left...right...left...right...left".
Same for skinning animals too. The game establishes that the main character is new to some of this stuff, so it would have been nice if he would improve at it. Then again, I don't know how they'd explain how looting enemies would speed up. I've gotten to the point where I just don't bother anymore. If I need money, bounties pay $400 for alive, and I'd rather spend 5 minutes doing that than 10 seconds to loot an enemy for $6.
