As a big fan of the genre I'm sad to say that there's not much else that looks like it.

Darfall is decent but lacks depth and variety. Having a hero Is nice, but the item drops can make or break your run.

I've yet to play age of darkness: final stand. But from what I gather there is not alot of variety in the endgame that can lead to a lot of wasted time if you're not doing the 1 thing that works 100% of the time.
