EDIT - This reminds me, the faster an ARPG plays the harder it is to appreciate the music. I am thinking of D3 here. So many sound effects.
For real, though sound mixing and the actual quality of a soundtrack are another important factor. Diablo 3's soundtrack is largely derivative and forgettable.
Fighting games can have a similar problem these days. Case in point: Dragon Ball FighterZ. The game looks and sounds stellar, but the overabundance of character voices for every. single. move. gets annoying and drowns out the BGM. Older fighting games showed more restraint on that front because they had to for technical reasons, but it turned out better for the overall experience. Sometimes, less is more.
[EDIT] About Diablo 1: played it back in the day, never made it far. Not even sure I beat the Skeleton King. Still, it was scary good fun. Replayed it to completion a few years ago, it's still a great game, if really broken. You can forget about using the Warrior because of blockstun. Wizard is clearly the superior class, and Mana Shield makes the game very easy. I never could finish Diablo 2 though. Got stuck before Duriel with the necro, and at the start of Act 3 with the Sorceress. Those damn pygmees...
