The best game for the PC.
Ya Diablo 2 was nice, but it didn't have a dark Gothic feel to it. It was more childish. With Diablo 1, I used to stay awake at night, making sure a 'carver' or 'scavenger' wasn't lurking under my bed, but with the sequel it just doesn't have the same feel. Anyone new to the series- play the original- its awesome! Best of luck for Diablo 3.
