I am a huge Myst fan and I have to say I loved Haven Moon. Since Myst I have played an enormous number of what may be called Myst clones, and Haven Moon is among the closest to recreating the original experience. The puzzle design and artwork are very reminiscent of those of Myst. There were a couple of puzzles I grew frustrated with because I thought I had to search a huge space of solutions, but after some patience (i.e. unlocking further areas to reveal more clues) and more careful observation and putting stuff together in my head, I discovered that there were sufficient clues to solve them with much less trial and error. The puzzles and exploration were fair, fun and rewarding. I played this about a year ago, and I'll be honest, I don't remember much about the story, but I do remember loving the whole experience.
