> Part 2 goes back to the Sierra model though, with puzzles that make little sense and are insolvable for most casual and moderate gamers without a hint guide.

Really? I don't remember having to look up hints a single time in part 2. The puzzles were more difficult, but definitely not "Sierra model". The solutions were logical if you paid attention, with the possible exception of the tree joke (I don't remember if that was part 1 or part 2).

The knot puzzle was probably the most annoying of them, but the problem with that one was having to take the long walk back and forth every time you failed.
