To be honest i wish i could skip the whole "playing the game" thing and just do endless "teleport to Baal, faceroll, reset" all night.
that was loads of fun. And leveling? that's boring. I would much rather stand at a stone while someone levels for me. that too, was amazing fun.
on a more serious note, I've extensively beta'd both Path of Exile and Torchlight 2 and am remarkably less impressed with them post D3 than pre. The lack of visceral feedback makes them feel paperthin, no matter what 'graphics/atmosphere'.
Path of Exile is probably the closest to a dated snorefest... I mean Diablo 2 if you miss it that badly.
