There were quite a few myst like in the 90s. Lighthouse: The Dark Being is one I enjoyed as a kid. Rheah is another one during that period. Cryo released an entire series of Myst like with Atlantis (not great though). Mystery of the Nautilus and Return to Mysterious island are decent though.

So, I'd say there were plenty of myst-like clones mostly focused on the European market though and not necessarily very successful.
