This may work if the developer is a possible client too like in this case. But I feel that’s the exception.

Do what the clients want and not what developers, designers or management want.

I would add Outer Wilds to the list.

You can really only play it once in a lifetime but I think it’s the best video game experiences available.

Honorable mention for Tunic and Cocoon for the same reason

For a game it has to be Outer Wilds…

And please do yourself a favor and play it the one time you’re allowed in this lifetime if you’ve not yet done it, as you can.

Other wilds as already suggested Is a must play. But a strong second contender for me Is cocoon. Logic/environment puzzles, with no hand holding in any way, you have to figure out everything but the level design Is sooo good.

Honorable mention for Tunic.

I had a “portable” 286 PC with DOS. And two games. Bubbles Bubbles and a game with two chimps throwing Bananas at each other.
