Would you have liked the opportunity to play London Life, the bonus RPG that comes with US copies of Professor Layton And The Last Specter? You can find out by watching this Professor Layton London Life gameplay video.
As you can see, it's nothing like a Professor Layton game. Indeed, you don't even play as Professor Layton. Instead, you create a character before setting out into Little London and running errands for residents.
By doing this you'll earn money which you can use to improve your home and buy new clothes.
As you can see, you'll meet various characters from past games in Little London. You can spot Sammy Thunder and Hank from Professor Layton And The Lost Future in the video.
