The Godfather of hack'n'slash.
Though I was happy already with the campaign once, I know fans that time who went through it hundreds of times just to level up their characters for online play. It just proves Diablo was a winner. The game still rocks even though its successor Diablo 2 is a bigger hit.
What captivates me actually is the music of Tristam, so eerie and exotic. It's the kind that lingers on in your mind even after you turned off your pc. Spooky but beautiful.
