Grim Dawn is a diablo-like ARPG, kickstarted in 2012 as the debut title from Crate Entertainment, an indie studio made up of devs from Iron Lore (who made the Titan Quest games). The devs describe it thus:

Players are thrust into the dark, war-torn world of Cairn where a once proud empire has been brought to ruin and the human race driven to the edge of extinction. Cairn has become ground zero of an eternal war between two otherworldly powers, one seeking to use human bodies as a resource, the other intent upon destroying the human race before that can happen. This cataclysmic war has not only decimated human civilization but is warping the very fabric of reality and, in its wake, giving life to new horrors.

I cannot recommend it highly enough if you enjoy the old-school style ARPGs. It hits perfectly on the loot-drop gameplay loop, class variety and differentiation, and world design (and it has excellent co-op!). Check out the homepage for guides, or the Steam page for the trailers.

It's on sale on Steam for $2.50 USD right now, which is 90% off of its normal price. It is an absolute steal at this price. If you're interested but still don't want to pay that for it, DM me.
