I'm not saying anything is wrong with it, just that I have too many fond memories of Diablo, and that it's not my ultra-most-super favorite game, (Nostalgic reasons...)
...but I did try the demo, and it does have the key features of Diablo that I enjoyed, and that's all I'm saying is "wrong" with me on Torchlight.
Fun game, just not the game best suited for me
