Simply put, I've never had this much fun with a dungeon crawler - Torchlight II is good shit.

It's a standard dungeon-crawler much like Diablo, but what really sets it apart is the art style and multitude of unique environments. The locales are so well-crafted and so atmospheric that they remind me of my old World of Warcraft days. Killing stuff is ridiculously satisfying (gibs included!) and looting as a whole is incredibly addictive and often suspenseful - you never know what kinds of exciting things could pop up.

Obviously, the whole thing draws a lot from Diablo and comparisons are obligatory, but I definitely prefer Torchlight simply because I adore the art style and diverse environments offered here.
