I didn't really mention anything about the breed of horses.. I know that Red Dead horses are different warmer breeds, but it is foolish to deny that the actual MECHANICS of Skyrim horse gameplay is better than Red Dead
It would be nice if they were improved, but I mean RDR was built around using horses, that was a huge major element of the game. Horse-riding in Skyrim is pretty much just to travel faster. I will say though, having played RDR some again in the week before Skyrim came out I keep pressing Y and wondering why I'm jumping next to my horse and not getting on it haha!
