Upon playing it again, I remembered why I stopped (other than crashes in Windows). It's BORING. Why? You have to spend points in a given spell (at least as a spell caster) and if you don't pack them into ONE skill you are too weak and yet by being forced to pack them into (mostly) one spell, at least early on, you are more or less forced to play through zoo loads of enemies and shoot them with the SAME SPELL forever. Picking up slightly better weapons that do little damage compared to your spell seems mostly moot as well.
Now I look at Borderlands 2 that I'm addicted to. It has TONS of gun combinations. Many are useless in the Ultimate difficulty level, but in Normal they're quite varied and fun to play with and you can always get a level editor to update weapons for Ultimate since the developers don't seem to "get" that having a legendary weapon (that rarely ever drops) become useless in two to three levels is ridiculous at that level. I digress. The point is that you have many situations where certain grenades, rocket launchers and varioius types of guns are NEEDED to get past various enemies (or cooperate with other players for even more strategies).
But in Torchlight, it's hit them with the same spell over and over, back off, use a potion to regain mana and hit them again. Rinse, repeat, pick up USELESS BORING treasure (also a problem in Borderlands to some extent) and then hit them again. Fun fun fun. At least Borderlands 2 TALKS a lot whereas these games with TEXT for instructions and conversations are kind of old in 2015 (Torchlight and even the new acclaimed Original Sin: Divinity are text happy mania as if we have no hard drive space for voice recordings and even BAD voice recordings are better than reading text as if I were playing Zork in 1977.
