I do find it a bit ironic people glossed over Torchlight II when it came out because of it's artstyle despite it's mechanics, when Diablo III overshadowed it which still didn't entirely inherit the visual aesthetic from Diablo II despite issues with it's gameplay and itemization which wasn't even improved until the Reaper of Souls came out. While Torchlight 1 and 2 may be a retread of basically of Diablo 1 and 2 but without the darker tone, story, and aesthetics of the former, all in all at the core the mechanics being solid making it a very overall enjoyable game to play. Skill trees are very similar to Diablo II with later skills adding synergy-like boosts.

Much like how Diablo 2 greatly expands over Diablo 1 with larger open environments, randomly assorted caves and dungeons with their own unique / champion spawns, multiple acts with different map environments, as well as several classes with their own unique skill trees and abilities, Torchlight II follows the same mold in the exact same fashion, as well as including the same pet mechanics from the first game which was essentially a carry over from Fate more or less.

In fact Torchlight 1's three classes pretty much ape the same Warrior, Sorcerer, and Ranger templates of Diablo 1. The original Torchlight 1 was super basic along the lines of the original Diablo 1 having a single labyrinthine dungeon that goes deeper and deeper and has thematic environment changes every 4 floors or so with newer enemies being introduced. Torchlight was more or less a follow up to the formula Fate utilized with a Main character + permanent pet companion that acts like a combined moving storage and D2 hireling.

Torchlight 2 was developed by the former remnants of Blizzard North's Eric and Max Schaeffer from Diablo II, and Travis Baldree who developed the Diablo clone Fate by WildTangent Games years ago.
