+1 for PoE. A bunch of friends and I had a weekend LAN party and took it for a ride. We all loved the additional features.
Torchlight II is another fantastic successor for this genre!
Eh. I can't say precisely what was wrong, but the Torchlight games didn't quite hit the mark for me. Some details I can put my finger on, though, include:
- The plot was, to put it bluntly, some of the most generic fantasy glop imaginable. The second game was particularly bad in this respect.
- Item generation felt... off, somehow. Some combination of too many item bases and too uniform a distribution of affixes made items generally feel kind of boring.
I personally found Path of Exile to be significantly better. Your mileage may vary.
Try Path of Exile [1] if you are looking for a spiritual successor. For me, that's the only game that comes close to Diablo 2.
