From the article, "Thanks to the 2012 Steam Winter Sale, we both picked up Torchlight II at 50% off and decided to begin a cooperative adventure involving dungeon crawling, loot gathering and boss butt-kicking.
What surprised me is how enlightening an experience this has been. Torchlighting, our name for our Torchlight II nightly runs, has helped me understand a bit more about ourselves as gamers and people after the experience."
