I remember playing (and enjoying, for the most part) "Two Worlds" years ago. It certainly was a flawed game, there were a lot of things wrong with it. But I also remember having a great time playing it. And the main reason why I'm bringing it up is because it is on sale for 90% off (ie. for $0.99). I'm not sure when I'm going to be spending time playing it -- but I couldn't pass up the sale.
I couldn't get through the start of Two Worlds II, particularly riding a horse, basic navigation, and combat in general. I gave up after a very short time. It all felt completely awkward to me (then again, I'm not the most coordinated person, so I'm sure that had much to do with it).
I persevered for a while but it just seemed to get boring after a while. Got quite a distance into the game twice but got bored eventually every time and stopped playing. As far as the horses go, I just ignored them because they were too much of a pain.
