I love this series for one reason. You have no idea what the hell you're doing.
Myst 3 has brilliant graphics, (at least for it's time) an wonderfully strange atmosphere, and nice, subtle background music. This game will offer you hours and hours and hours of fun and frustration. The puzzles in Myst games are really hard, but that's why everyone loves them. Or at least everyone who does love them loves them for that reason. Another great thing about this game is the feeling of being alone and confused in a strange, realistic world. This is very hard to describe, but it's what really gives the Myst games their charm. Especially 1,2, and 3. This is one of the most fun and interesting games that you'll ever play, if you like this type of thing. If not, you'll want to throw it out the window because it's too hard.
