So far the game has been pretty fun. There's been a few little problems I've had but nothing really that bad. For example I was just riding along exploring when I heard a lady yelling for help cause her wagon was stolen. I caught up to the wagon, killed the guy and when I got off my horse to drive the wagon back, my horse just ran straight towards the wagon, knocking it over and destroying it, then turned around and walked back to me.
edit: just did another one of these things where I had to save a guy's horse. As soon as I killed the guy that stole it, the horse walked straight into the river and died.
