crawl VS NetHack

It's probably not as rigorous as what you're thinking of but the devs of DCSS have cited online win rates of certain combinations as the impetus for balance changes before.

In a similar vein, see Dungeon Crawl Stone Soup, a free and open-source roguelike that's been continuously developed by volunteers for 20 years: http://crawl.develz.org/

They are entirely too humanoid. I mean, look at these splash screens: Kiku, Ignis, Chei. While those images shouldn't be taken as canonical, they at least demonstrate the general inhumanity of the Crawl pantheon.

Since you like turn-based games too, try some old-school roguelikes. Many are open-source freeware so you have nothing to lose but time. I've been playing Dungeon Crawl Stone Soup for almost 10 years.

Since Brogue's already been mentioned, I'd add Dungeon Crawl Stone Soup and Tales of Maj Eyal as pretty beginner friendly games.

For people who don't follow trunk, Okawru's gifting has been changed (and arguably* nerfed):

My personal first timer recommendation? Maybe Nethack or Dungeon crawl?

Dungeon Crawl Stone Soup - Free traditional roguelike with fair mechanics and a lot of variety between species/skill/god choices (~25 gods and maybe with the exception of sif/veh and oka/trog, they are very distinct). The tiles are great. There's many developers and they are very welcoming of code or vault contributions. Reducing incentives to play tediously is one of the goals. Easily hundreds of hours of gameplay for free. Playable online (connecting to a server through your browser/terminal) or offline (terminal or tiles version). There have been win streaks of 50+ games with a variety of species/background combos so you know it's mostly fair(it IS possible for rng to give you an unwinnable game), but it's very difficult if your goal is to win every game.

My configuration of Eglot is simple: (use-package eglot :hook (c-mode . eglot-ensure)). And it works for a single c file. But when I use this setup to read the code of NetHack, it doesn't work for linting and definition finding (M-.), even though eglot connection has no problem. I observed the same problems when reading the code of SQLite. Some specific problems I observed:

Since nethack 3.1.0, the source for nethack's "bestiary" has been dat/data.base, in plain text, processed into a file named "data" when building the program. The unprocessed file intended for the nethack's next version can be seen at https://github.com/NetHack/NetHack/blob/NetHack-3.7/dat/data.base (it's quite long).

I am not really 100% sure what you are looking for. Are you looking for the actual picture? It is built during compilation from this uuencoded file https://github.com/NetHack/NetHack/blob/NetHack-3.7/win/win32/splash.uu

xNetHack is based on NetHack 3.7.0, and there was a bug (now fixed) in NetHack 3.7.0 that caused stair destinations to be messed up after a game is recovered. I wonder that has happened here: perhaps you are playing a version of xNetHack that inherited the bug from NetHack 3.7.0, this is a recovered game.

They won't be afraid of music in 3.7.

This is a bug that was fixed in the upcoming 3.7, in this commit. Basically, if the random filler created a space that was made inaccessible by the fixed level design getting overlaid on top of the random filler, a door could be created to make that space accessible.

There is not a comprehensive list of changes in existence. This one comes close but doesn't contain everything https://github.com/NetHack/NetHack/blob/NetHack-3.7/doc/fixes3-7-0.txt

I have an open github issue requesting that intrinsic invisibility be made only temporary, not permanent. That would make the invisibility mechanic more interesting since you could decide multiple times per game whether you want it, and extrinsic invisibility items would become more useful.
