It would be nice to one day have graphics that nice. Reflective water and Hi res grass.
But like many said, not every one's computer can run it. I know one of mine can. My laptop was built to play games and has a nice graphics card. But not every one has my laptop or nice graphics cards. My other computer can run AH but only with the graphics settings set low.
And making that high quality graphics would take forever to make.
But I would not mind having Hi res, but we will have to wait for some thing like that. If HTC did add those graphics, there could be a setting fo those who have higher end graphic cards to have these settings. But then have them off for the lower end graphic cards.
