Skyrim's puzzles where you have to find the matching claw and put the three animals on the door in order was fine. The 3-6 3-sided stones were a waste of time. LA Noire's mission where you had to decipher the poems to find the location of the next clue were time-consuming but good. It just depends on 1, if they do it and 2, how they do it. Puzzles can make or break a game.
