Query: Fun but Overly Difficult

It's tough to pick on the Myst team(s) for making a game that is too difficult...that's always been the appeal of Myst to me. However, the main puzzles in this game, while fun to play, are not likely solvable by most logic-puzzle gamers. The solutions are not very intuitive, and there are often few if any clues leading to the solution. Without spoiling anything, let me just say that you need to be patient...VERY patient...not just with yourself but with the puzzles themselves (i.e., be prepared to do nothing at times). I don';t know how I could have gotten through this game without looking at a walkthrough for at least 4 of the key puzzle solutions. A mediocre effort by UbiSoft. Hopefully, Myst IV will be better.
