And some game recommendations by me to add on to the post:
Taiji
A 2D puzzle game where you slowly unravel how to solve each different element of the puzzles, eventually culminating in a massive puzzle gauntlet. Basically identical in concept and execution to The Witness, but still very much its own unique and fun game.
The Golden Idol
A puzzle game where each level you must examine a scene to figure out exactly what happened, eventually piecing together the full story over several levels. Don't let the art style put you off, it's an incredibly well done game. Most similar to Return of the Obra Dinn in concept.
Stories: The Path of Destinies
an action RPG with a branching choice-driven storyline, but not every story has a happy ending... You'll piece together the true story over multiple playthroughs and eventually find the one true path. It wasn't a particularly life-changing game but it was still a lot of fun and worth checking out if it sounds interesting!
I'm always having to learn new practical skills for work, and getting into things I know nothing about and having to learn them to be successful.
The difference is that the skills you learn from playing games usually are not transferable to the rest of your life. There's some exceptions to this but most of the stuff you learn from complex games are completely fabricated for the game and have very little bearing on real life.... Though, am argument can be made in many cases, such as kerbal. I haven't played kerbal, but I understand there's some reasonably accurate orbital mechanics and rocket science involved. This is just one fairly obvious example that I know of. Not to be confused with a comprehensive list of games with practical educational value.
For me though, I usually don't want to learn anything useful while playing a game, since that's basically what I do for work. So any game, like our example of kerbal will, in all likelihood, feel like more work to me, which is decidedly not the objective I'm going for by playing a game.
I dunno. Different games for different folks or whatever.
I don't think that's what they meant. More like where the game doesn't hold your hand or suddenly give you knowledge of things that you don't learn through playing. Like in outer wilds where the game really gives you almost nothing to direct you at first, you have to learn what's happening and how to progress. But once you know it, you could technically finish the whole game in only a few minutes as it's entirely deterministic and won't gate you from content just because you didn't do an arbitrary condition to reach it.
