Grim Dawn is pretty good fun, its based in the Warhammer universe and there are 8 playable classes to choose from (with the recent expac) and you can combine 2 classes to combo stuff together. It's got all your usual stuff from a dungeon crawler and I'm really enjoying it atm.

What about this? Tales from the Candlekeep: Tomb of Annihilation.

I don't play too many dungeon crawlers but the best ones I've played were Baldur's Gate Dark Alliance on PS2 and Diablo 3. Those two stick out when it comes to best dungeons crawlers.
dont forget the Wizardry series brilliant,

Not to hijack your thread, but I see a lot of top-down games. I like them too, but I've been wanting a game in this genre that's either 1st or 3rd person. Any solid recommendations?
