OpenLara VS crawl

I didn't notice anything suspicious in his explanation of how the AI works, though he glosses over navigation. I assume he is using the OpenLara engine, in which case he easily has access to level geometry or other parts of the game at runtime that would normally be inaccessible. However when watching the AI play, I got the impression there was two much overlap between what the AI does and says. For example, based upon what I understand of the explanation of how the AI works, the part playing and the part talking are not interacting with each-other. Voice lines are simply generated based upon what is on screen and there is no true common intent behind the AI's actions and speech. This makes me suspect the entire video is simply a scripted imitation of AI.

You can try source engine ports like xash3d diii4a Serious Sam Freedoom OpenLara Quad Touch and Source Engine

It is, it’s the OpenLara engine, so it’s running native code rather than emulating the PSX version.

OpenLara

You can play it online here, the github link on the page also has a downloadable version that plays offline and works with the controller. http://xproger.info/projects/OpenLara/

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.
