in diablo 1 you had to click for every single attack of your character. In diablo2 you didn't have to do it, however most of your attacks would be special attacks, meaning you would have to click all the time anyway (except maybe if you had a skill that you could use all the time while holding). I usually played the assassin and had to click nearly as much as in diablo 1. However, it was enjoyable either way to me. More relevant for the enjoyment in "feeling" would be the sound of your hits and if it really felt like you hit them visually. In my opinion e.g. Titanquest couldn't get that feeling right. However, Diablo 3 and Path of Exile could (Torchlight is okay in that regard, but not quite as good). Still, my favorites remain Diablo1+2.
I've really come to enjoy Good old Games https://www.gog.com
They have Diablo 1 (+ Hellfire) available for 9.99 (but goes on sale)
(That said there's a huge "Do not sell my personal information" link on the diablo page)
I have enjoyed torchlight 1 and 2 quite a bit. It's been a while since I played diablo 1/2 so I can't compare in my head. I recall there was more clicking in diablo.
