Closest I've seen to Myst/Riven – Hidden World Review

The puzzles are well-designed, with the clues to their solutions being wonderfully balanced--the clues won't blatantly give you the answer, but they're clear enough that you'll be able to tell which clue goes with which puzzle. It probably gave me a total play time of 2-3 hours split across three days.
