As far as I have seen, HD hasn't changed a game in quality in graphics from an HD and SD tv. So I was wonder, why is there such a great demand for getting one or that a game can handle HD. I have only tried it on Fallout 3 and some demos with no difference in quality of graphics. In fact Fallout 3 looked even worse in HD then it did in SD. So what about HD makes it better? I ask because I can't seem to find a reason why.
