A recent update to Torchlight has added achievements to the game. There's no way to see them in game (which is a bummer), and I wish they had progress bars that gave you an idea of where you were in the midst of collecting each one. Those nits aside, this is a great addition to an already great game. As of this writing, I'm only 15% complete, but I look forward to trying to grab as many as I can. Some of them look awfully difficult! It's a shame they didn't have this in the game from the get go...

Update: Here's the global achievement list for your perusal.
