Portal is trivial and Talos Principle is good but a bit contrived. I have never played a puzzle game that I considered a chore. The puzzles are the game. You don't need a story or a point in them. I also play chess and there is certainly no immersion or physics in that.
The Witness also has the sublime revelation in it that makes it more memorable than most games. I don't even remember the god's name in TP, but I can envision clearly every Witness locale.
I guess crosswords, chess, sudoku, solitaire, and competitive programming need to add plots and narratives to their next editions, lest they be thought to have pretensions! (Of what?)
I enjoy all of the above and not the bland, droning, tasteless, pointless "learn the next mechanic" JB games. YMMV.
BTW the talos principle AI referred to itself as yahweh, if you ever read the bible.
Edit: and chess is uniquely lore-heavy. Even the openings have openings and everything is tied to history. I'm surprised it is even brought up in comparison at all.
