Same as always but with new addtions.
Presentation: The Professor Layton series is known for its cartoon style that is simple yet likeable; this remains true for the Last Specter. The characters look good and Layton's hat is as tall as ever. Dialogue is also another Layton staple and there is an abundance of it. Conversations never seem useless but they can get boring. People that hate to read, BEWARE! It should be noted that not every conversation is done with text boxes; there are the occassional cutscenes, but they are too sparce to really take the edge off. The story is (in my opinion) one of the better Layton stories. It's more interesting and has a few good plot twists. Fans of the series get to see how Layton and his apprentice, Luke, met which is a nice touch and adds some depth to the Layton universe.
Gameplay: If you've played a Professor Layton game then you know how this goes. You go from point A to point B using point-and-click mechanics. While travelling around, you encounter puzzles that need solving. The puzzles range from hard to kind of easy without being too extreme in either direction. They are also varied. Enough said on that really.Where this game really shines is in its extras. Level 5 did an awesome job with the extras in this game. There is so much to do in and out of the stroy; there's mini-games and even a full length RPG to play outside of the main adventure. The RPG is called London Life and that's a totally different thing to talk about but it adds over 50 hours of gameplay to The Last Specter. Level 5 also added additional puzzles as DLC. There is never an end to the game, if you think about it.
Conclusion: Professor Layton and the Last Specter is the same usual Layton formula but with tons of extras added onto it. If you're a Layton fan, then you will enjoy this game. If you hate reading...not so much.
