This draft has been sitting for 22 days on my account, time I take care of it lol
In terms of recommendations the first thing that feels like it needs to be addressed is which kind of dungeon crawlers we're talking about. Lunacid and the games in which it's based (FromSoft's output with King's Field, Shadow Tower, Eternal Ring etc.) are first-person real-time, where the majority of games labeled as "dungeon crawler" tend to be the typical grid and turn-based affair. Then there is also the matter of the perspective, and if you want to exclude everything that is not first person.
I admittedly can't think of too many games of the first-person real-time variety. Probably the closest thing that comes to mind is Saturn/PSX **Baroque**. Very maze-like and esoteric, and first person with real time combat as well. It's a very known and beloved game in these parts, which has [its own thread here](https://forums.insertcredit.com/d/311-baroque-on-the-saturn).

There is also **Hellnight**, which is more of an adventure game (no direct combat), but gives very similar vibes. Exploration takes place in maze-like environments in real time and has those distinct weird PSX hellscape environments, with horror elements thrown into the mix.

If that works, then there is also FromSoft's **Echo Night** games (there's a few of them), which works within similar parameters. First person with no grid, also more adventure-like with no combat but some horror elements.
The next thing that comes to mind is **Arx Fatalis**, Arkane's spiritual successor to the Ultima Underworld games that are generally considered to be the "founders" of the immersive sim sub-genre. Underworld of course would qualify, although the controls, UI and UX may be a little bit dated.

Lunacid is more Japanese-flavored than Arx Fatalis (aka more gated progression, less system-based design and prone to emergent stuff) but in terms of general vibes and feeling I think it's a good rec. Arx is a great game anyway, fantastic vibes, good exploration and environments and a very unique magic system. If anyone feels like giving it a try I recommend using the [Arx Libertatis port](https://arx-libertatis.org/download), which leaves the content untouched but provides very welcome QOL improvements and conveniences for modern systems like widescreen support and all that jazz.
If we count Underworld and Arx then the original **System Shock** also could work too. I know I'm progressively moving further away from the premise but bear with me! The environments are very maze-like in a distinct dungeon crawlery way. Combat is real time and no grids also! If the old game looks intimidating the recent remake is very faithful to the original and is also a great choice. SS2 still has RPG elements but the level design veers away from the maze-like design.

I was wondering if I should mention them because they are extremely not dungeon crawlers, but the feeling of loneliness and immersion they give me is so similar that I'm gonna throw them as a honorific mention of sorts and let you guys decide: the first time I played King's Field I couldn't stop thinking about the **Metroid Prime** games. Yeah, as I said, very much not a dungeon crawler.
The **Legend of Grimrock** games are somewhat real time but grid based. Good games anyway, with a puzzle design I'm very much into.

The grid + turn based variety is easier to come across, here a couple of deep cuts (deeper than usual anyway) that you may like and are also available on modern platforms:

(Zanki is from some of the Dangaronpa devs, if that catches anyone's curiosity)

(Refrain has a sequel, both games from Disgaea devs)

Finally, a couple of games that are not on first person but I think are cool anyway:

(Some of these are traditional roguelikes but there's huge overlap between these two genres anyway imo)
