I'll say three things:
1. It reminds me of Diablo 2.
Diablo 2 was, quite easily, the best ARPG ever made. For me personally, the Torchlight 2 Beta damn near stole that crown, but nothing will take Diablo 2's spot in my teenage years. Anything that reminds me of my countless hours leveling one of each class to 99, farming loot, trading items and PvPing with randoms and friends alike is a good thing. Even Diablo III.
2. It's a solid example of what not to do.
Basically, everything Diablo III did is wrong. Nothing it added, or subtracted, made for a better experience. Luckily, it's such a shining example that all other game developers have an easy example to use to make better games so we don't have to suffer this trash again.
"Let's put Always Online DRM in our game! And Auction Houses!"
"Fuck no - look what happened with Diablo 3!"
"Gee - you're right. Let's avoid that land mine!"
3. Torchlight 2.
Luckily, thanks to Diablo III being more closely related to World of Warcraft, I avoided Diablo III. And, in doing so, I discovered Torchlight 2.
I cannot under-state how much better Torchlight 2 is compared to Diablo III.
Without Diablo III basically spitting in the face of everything from fans, journalists, common sense, reason, logic, rudamentry game design understanding, etc., I'd have jumped on board for this entry, and missed Torchlight 2.
