Torchlight took everything that made diablo 2 work and made it roughly 10,000x better. It's no wonder, too, as Runic is mainly composed of the former Blizzard East employees charged with creating Diablo 2 in the first place. From the ability to create endless variations of the same class to the random dungeon generator, not to mention the Sword of Adam (WIZAAAAAAAAAAAAAAARDS!) This game was a masterpiece and the TRUE spiritual successor to Diablo 2.
