Wow, all I can say is this game is an absolute gem. I cannot remember the last time I played a game that I had this much fun while playing. This is an extremely well done hack and slash action/rpg, plays very similar to Diablo and Fate (which I finished a week or two ago as well), but there is something about this game that is head and shoulders better.
Whether it is the cute cartoony art style, or the simplicity of the game play mechanics, probably a combination of them all. By the end of my first play through, my character was so overpowered that I was one hitting enemies and taking bosses health down by half each swing. I was a slow mace duel wielding warrior and it was hella fun.
Another thing I like about Torchlight is there is endless replay-ability, once you finish the game, you open up a new dungeon with infinite amount of levels, each floor is randomly generated with enemies which scale to your level. This is a game to keep installed once you finish as there is plenty of reasons to keep coming back
