If you were a fan of the original, you don't need me telling you to buy it  (you probably already have it!). If your new to Diablo, or if this genre of  game is not your thing, you may find the graphics a little substandard.  Don't get me wrong, its a good looking game. But if your used to the 3D  accelerated hi-res graphics of some of the first person shooters out there,  this will look "different" in a way that might be interpreted as  "low-res".
