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.

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

Seems so. Checked the sources and there’s no upload/download. And testing it I can confirm the network tab in the dev tools is silent. Everything work local side. Probably with some additional work this could be converted to a PWA (Progressive Web App) and work completely offline.
