Charming
This game is interesting how it is one of the first first-person games that doesn't have a restricting storyline. What I mean is, it doesn't feel like your watching a movie, but that you're sucked into someone else's world, like what you are playing is real. There is an extensive backstory to read as well, which explains why certain things are the way they are in the game. The gameplay itself is rather minimal. You point and click and point and click and point and click. But this was also made in in 1995 and the game is a puzzle game so it doesn't bother me too much.
It's a good game. I consider it a classic to the series, which the only game I think that may be better than Myst is Exile, or Myst III.
One warning however.
If you are not prepared with a paper and a pencil, this game will be very frustrating to play. You will need to write things down.
