This is the game of Myst, recreated in Minecraft. All of the puzzles intact, however many are a bit simplified due to space restrictions from redstone. There are now videos from the original game included, as well as .txt versions of the journals from the library.

All the main ages are complete, including their puzzles, Rime may get added later though it doesn't really have any puzzles so it's not that interesting in my opinion.

Here you can follow all the work that went into this, and get the most up to date download, and check out some photos and videos of it all

Make sure to download the videos here as well
