Yeah well, to be fair, aside from Hades, Diablo, and Baldur's Gate, if you've played one dungeon crawler, you played them all; I'll take whatever fresh new aspect on the genre I can get
This comment is just meant to inspire you. Should you not have played the mentioned games.
Legend of Grimrock 1 and 2 were also masterpieces in an on themselves. The atmosphere is impeccable.
The
Bunny Black series while not on the same league still felt special. Only in the start did I do it for the prawn. I remember in the second game. I wanted to have disciplined jet black knights so badly. Bit of the spectral 'tism on my behalf, I guess.
Noita, Binding of Isaac, Darkest Dungeon 1 (screw the sequel), and Enter The Gungeon are also technically dungeon crawlers. They feel nice to play once you have mastered the systems. It was a headache forcing myself to clear everything with the default gun in Enter The Gungeon. However, once you get to that point all the worries just slip away (at least for me).
Dungeons of Dredmor and Dungeonmans are games where you have to learn to laugh at yourself and not take everything so seriously. They'll drive you insane otherwise. The lore of the games is not so much in the idiotic messages, you get along the way. It's really felt in the areas of the different dungeons. Everything changes and you have to adapt.
I've spend so much time in
Slormancer. Although, it's mostly a brain off kind of game, especially once you've made incredible builds for your characters. Despite having many hundreds of hours into that game. I don't really know, if I can recommend it to other people.
Ring of Pain is more of a card game despite also being marketed as a dungeon crawler. I mention it, because I so adore that game. Finding out good combos, the lore, and the monsters/areas yourself is really rewarding.
Nightmare Reaper is an FPS dungeon crawler. There are so many goofy builds and so much fun in this game. It is a dungeon crawler with many solutions to any given problem.
