A lot of good suggestions in this post, but the only real answer here in Minecraft Dungeons (only half joking).

A game nobody has mentioned yet would be Undecember. Instant dont play if Korean MMO, f2p or an in-game shop scare you away. Behind all that is a pretty good arpg with unique skill combination mechanics that are a joy to experiment with. Beware though that if you want to get really far, the grind won't stop. (Progress can be bought, generally it's just not worth it though, only p2 play hurdle is inventory space and that's a one time payment of 20-40€ depending on you) I`d recommend checking out a guide or two concerning runes before jumping into the campaign as it can be a bit challenging in the early levels, especially if one doesn't use all the skills available.

There are many good games listed here. However, focus on Path of Exile. It´s what Diablo 3 should have been.

There's a game on game pass that I recently saw called Ghost Lore that I think claims it's inspired by Diablo? Might be worth checking out

I'm not sure if you are looking for anything on a specific system/console but I have a few suggestions. The first one being Baldur's Gate: Dark Alliance and it's sequel. Eternium also looks pretty good, especially for a game that was originally exclusive to mobile. I unfortunately can't say much about these games because I have yet to play them for an extended period of time but I have played them enough to know that they are at least similar to the Diablo games.

I am also aware of some other games that might be worth checking out but I'm not sure how close to the Diablo games you are looking for and they are quite different from the Diablo games.

Diablo

Yes.
