Agreed, D2 is/was the pinnacle of and set the benchmark for two-dimension dungeon-crawler RPGs. It's still an enjoyable game even 20+ years later. It's probably a good thing there's no Web/Android/iOS version because I'd be hooked, and don't have time for that anymore!
I grew up playing an inordinate amount of Warcraft I, II, III, and StarCraft in the 90s with my siblings. The quirky character voices and scripts were downright amazing and AFAIK remain unparalleled to this day.
