Ignoring that all of this is solvable by using the "GIF plays X" solution I was thinking about what could be done to make Myst work in a post.
Of course sound won't work, but I'm pretty sure there's a combo of "only play once" gifs and "repeating" gifs that would allow for the opening sequence at least.
With the latest graphic novel tech, it seems like there's support for interactive cyclical graphs, which would allow navigating at least part of the main island.
Probably each individual puzzle or object would need to be left out (or carved out into its own post?).
Eventually there would be a constraint of post size, but I think there's room for some interesting prototyping before reaching that limit.
Realized tonight that @nex3's cursor original css crime means that it could be possible to have different parts of the chost show different "cyan games hands" to indicate what direction clicking would take the player
