Roguelikes are defined by permadeath, quick runs and procedural generation. Diablo 2 and Torchlight have the latter, but they are quite old, and the resurgence of roguelikes is relatively recent. I believe it's just has to do with it being a very solid (and addictive) gameplay model, and one that fits much better indie games than AAA titles.
