Soulbringer is a good suggestion. It's heavy on (non-party) combat, but it does care about its story. The latter isn't anything to write home about, but the game has a particular, unique feel to it. Not least because of the dark snowy wasteland early on and the interesting exploration around there when the story is still mostly a mystery, but also since the combat system is a bit unusual. Later on magic is added and it is another aspect of the game which is fairly interesting. Basically, your character can only be good at one element at the expense of the others. I'd recommend it just for how unique it felt to me as I was playing through it some years ago. A warning though: I had issues with the game running too slowly which only was fixed once i switched to a different Direct-X renderer (gog-version).
Other than that, it also seemed like a good idea to point out Dawn of Magic, which was made by the russian company Skyfallen Entertainment. It's a Diablo-like, though one which doesn't have a class-system, but rather a spell-combo system. In some ways it's fairly similar to other ARPGs, but certain things like the character building system are handled a bit differently. Same goes for the large maps and large cities. Good music, though the story is - again - nothing to write home about. It's not available on the digital services for some reason. Dawn of Magic 2 is, but that one is just a shorter stand-alone expansion that is lacking in comparison. Simply get a used copy off of amazon if need be.
And third, another Diablo-like: Restricted Area, by a german company. Another case where you would have to get a used copy from somewhere. It takes place in a postapocalyptic scenario mixed in with a dose of cyberpunk. However, the world only consists of basically one street and randomly generated maps. Some good music and overall ok atmosphere I'd say. Try it if you are interested in mixing guns, cyberware and bioware (but also swords in one case) into the usual formula. The story in this case is kind of painful at times, but it varies somewhat based on the chosen character.
Edit: I just remembered that the most recent patch for Restricted Area was giving me trouble with mini freezes during inventory interaction. Once I went back one patch the problem disappeared.
And another thing: Perhaps somebody has played Abomination - The Nemesis Project more extensively than me and can comment on it. I only played the demo many, many years ago, so I can't say much about it, but it always looked fairly interesting. Group-based tactics in real time or something like that.
