I loved that game. Might be interesting to try again. Man, Myst seemed so revolutionary at the time and I sure loved the concept of there being no instructions, you're just plunked down in a world and figure out that there's stuff going on.
Honestly, it looks great. I think it has retained some of its original charms, visually.
I was only marginally aware they were working on a remake, and I just learned it will be available for VR. Apart from art/media crossovers in exhibits, I have not touched VR, nor did I have any desire to, but I can see it working for something like Riven. Maybe I'll try that.
There seem to be some changes / additions to the original game? For example I don't remember the house/dome thing on the giant tree stump (~30s) or the tree (at the end of the trailer).
The house on the giant stump is where Catherine is being held captive.
One of the things about the original game is you were locked to certain viewpoints which made it a lot easier to make sure players picked up on details; you couldn't just walk through an area staring at the sky etc. but you couldn't take in your surroundings. There's a lot of details about the environment that was always there but is difficult to know about because there aren't any perspectives that look at them.
Looks like they did a great job keeping the visual aesthetic of the game, fairly realistically rendered environments and textures. It looks like Riven.
