I still play D2 thanks to the hard work at the folks running Project Diablo 2[1]. Perspective mode looks absolutely beautiful at 144fps; it's somewhat hard to go back to the 30fps of the original LoD client.
Even now, I still have the memory and nostalgia of walking down the twisting steps from the Pandemonium Fortress and being blown away by the beautiful (macabre is maybe more fitting) graphics.
