What was broken.... ah. This is what I remember from playing.
- I lost a character because one of the puzzle map segments glitched out in the campaign and there was no way to reset/regen the map. Stuck forever.
- The Alchemist's "caster" tree only had 2 spells that would scale with any damage type.
- The... transmuter, was it? The horadric cube in NPC form never worked right for me. Gems in particular seemed random; I could put in 1 small gem and it would cycle through every quality, then to another gem type.
There's also the fact that half the skill trees for every character were the same (the "adventuring" skills) which seemed disingenuous to me. +axe skill spawning on a 2H crossbow. Arrows that can't fly to the edge of the screen. Paying an enchanter to strip your items of every mod. Set piece gear with random mods, so... pretty much entirely useless. Fishing (the worst).
I'm a big fan of aRPG's; I loved Dungeon Siege (2 mostly), Titan Quest/Immortal Throne, That Game That Can't Be Mentioned Here, and even hybridized stuff like Dungeon Defenders (haven't gotten to Orcs Must Die yet). Torchlight just seems like a bare skeleton with some clothes stuck on it, that could have been great, but wasn't. There's plenty of polish but no substance or longevity. The more I played, the less I liked. I'll probably check out Grim Dawn and That Game That Can't Be Mentioned Here 3, though.
