To find the sequel, its hard.
Yeah, you can try LOD if you haven't played it. It has tons of great add-ons. Perhaps you would want to update your version of Diablo 2 LOD (when you bought it), to patch 1.10 if I'm not mistaken ('ve already stop playing D2 LOD over a year).
I played Sacred, Temple of Elemental Evil and Neverwinter Nights, it gets me bored so soon.
