Diablo 3: Gameplay

Hi Everyone,

Haven't got the game but have been reading about the extensive server errors and bugs. Those parts aside, how is the game itself (if you have managed to play yet)? I love Diablo 2 and am wondering if the game play is up to scratch? Is the story enthralling and classes fun? What are your thoughts and impression on the game so far and is it worth the money or should I stick to Torchlight?
Many thanks for your replies :-)
