I didn’t understand it the first time I played it (I was quite young). But I loved the music, the environment, the aesthetics, the architecture.

If you like Myst, but found Firmament missed the mark (I feel like it was “follow the wire” and “look for hard to see thing” instead of myst puzzles of “information way before you need it”, or “puzzles way before you have information”), check out Quern: Undying Thought.
It nails the Myst experience, imo.
