I know that it was or is a game changer Arpg with tons of mechanics, loot, customization etc etc.
I sincerely tried to push myself through it a couple of times, but every time I was stopped by ugly UI and most importantly- the ugly loot. The loot in this game doesn't look cool, at all. I just don't like or even dislike the art-direction of it, I'm sorry.

Where Diablo 4 has an ok loot but they made it so small on a screen that I barely can see it, here it is in your face, but looks ugly.

I believe Diablo 2 (especially D2 Ressurected) is still unbeatable and a master class in art direction and design.
