As an absolute Professor Layton fan of course I had also the third part of the series have ... Just like during the previous parts of the Professor Layton player expect here new and challenging puzzles of all kinds. As always perfect success and once again a new challenge. I would buy the game / the game series at any time. Even my kids (7 and 4 1/2 years) love to play the games, and even the "small" can solve some puzzles already own.
The only drawback: I think the "conversations / dialogues" between Professor Layton and Luke sometimes very very long and even annoying. Most players should probably go to the puzzles and not really about the story ... This can make shorter my opinion. I am already looking forward to the fourth part ...
